## FAQs

**How do you find the reflection of a point?** To find the reflection of a point across an axis, negate the coordinate that corresponds to the axis of reflection. For example, if you want to reflect a point (x, y) across the x-axis, the reflected point will be (x, -y). Similarly, to reflect a point across the y-axis, the reflected point will be (-x, y).

**What is a reflection in math calculator?** A reflection in a math calculator refers to the transformation of a point or a shape across a line or an axis. This can be done by changing the sign of one of the coordinates (x or y) while keeping the other coordinate unchanged.

**How do you reflect on a graphing calculator?** Graphing calculators often have built-in functions or menu options to perform reflections. You can typically find these under the “Transformations” or “Graph” menus. To reflect a point or a graph across an axis, you input the original function or point and specify the axis of reflection.

**How do you find the coordinates of a point reflected across an axis?** To find the coordinates of a point reflected across an axis, negate the coordinate corresponding to the axis of reflection while keeping the other coordinate unchanged. For example, to reflect the point (3, 4) across the x-axis, the new point will be (3, -4). To reflect it across the y-axis, the new point will be (-3, 4).

**What is the 3 rule of reflection?** The 3 rule of reflection states that the image of a point reflected across an axis will have the same x-coordinate but the y-coordinate will have the opposite sign. If the original point is (x, y), the reflected point will be (x, -y) if reflected across the x-axis, and (-x, y) if reflected across the y-axis.

**What is the basic formula of reflection?** The basic formula of reflection for a point (x, y) across the x-axis is (x, -y), and across the y-axis is (-x, y). For reflection across the origin, it is (-x, -y).

**What is the rule for the reflection?** The rule for reflection across the x-axis is (x, -y), for reflection across the y-axis is (-x, y), and for reflection across the origin is (-x, -y).

**What is the reflection of X Y?** The reflection of the point (x, y) across the x-axis is (x, -y).

**What is a reflection in math graphing?** In math graphing, a reflection refers to the transformation of a point, line, or shape across an axis, such as the x-axis, y-axis, or the origin. It results in a mirrored image of the original point or shape.

**What is a reflection in graphing function?** In graphing functions, a reflection refers to transforming a function’s graph across an axis or a line, resulting in a mirrored image of the original graph.

**How do you reflect a point across both axes?** To reflect a point across both axes, you perform two separate reflections, one across the x-axis and another across the y-axis. If the original point is (x, y), the reflected point will be (-x, -y).

**What is the reflection of the point (-2, 5)?** The reflection of the point (-2, 5) across the x-axis is (-2, -5), and across the y-axis is (2, 5).

**What are the 2 basic laws of reflection?** The two basic laws of reflection are:

- The incident ray, the reflected ray, and the normal to the reflecting surface all lie in the same plane.
- The angle of incidence is equal to the angle of reflection.

**What is an example of rules of reflection?** An example of a rule of reflection is that the reflection of a point (x, y) across the x-axis is (x, -y), and the reflection across the y-axis is (-x, y).

**How do you reflect across Y = -1?** To reflect a point across the line y = -1, you negate the y-coordinate of the point while keeping the x-coordinate unchanged.

**How do you reflect across Y = 3?** To reflect a point across the line y = 3, you negate the y-coordinate of the point while keeping the x-coordinate unchanged.

**How do you solve reflections in geometry?** To solve reflections in geometry, you need to understand the axis or line of reflection and apply the appropriate rules for reflecting points or shapes across that axis or line.

**What is an example of reflection in math?** An example of reflection in math is reflecting a point (2, 4) across the x-axis, resulting in the new point (2, -4).

**How do you know if a graph has a reflection?** In a graph, if you notice that the shape of the graph remains the same, but it is a mirror image across a particular axis or line, then the graph has undergone a reflection.

**What is the reflection of the point?** The reflection of a point is its mirrored image across an axis or a line.

**What is the reflection of point (3, 4)?** The reflection of the point (3, 4) across the x-axis is (3, -4), and across the y-axis is (-3, 4).

**What is the reflection of point (6, 8)?** The reflection of the point (6, 8) across the x-axis is (6, -8), and across the y-axis is (-6, 8).

**What is mirror formula?** The mirror formula in optics relates the object distance (u), image distance (v), and focal length (f) of a mirror. It is given by 1/f = 1/v + 1/u.

**What’s the angle of reflection?** The angle of reflection is the angle between the reflected ray and the normal to the reflecting surface. According to the law of reflection, it is equal to the angle of incidence.

**What is the difference between reflection and refraction?** Reflection is the bouncing back of light or other waves when they encounter a boundary between two media, while refraction is the bending of waves as they pass from one medium to another at an angle.

**How do you write a reflection rule in math?** A reflection rule in math can be written as follows:

- For reflection across the x-axis: (x, y) â†’ (x, -y)
- For reflection across the y-axis: (x, y) â†’ (-x, y)
- For reflection across the origin: (x, y) â†’ (-x, -y)

**What is reflection for dummies?** “Reflection for dummies” is likely a casual way of referring to an explanation or introduction to the concept of reflection in a simplified and easy-to-understand manner.

**What is reflection in 3 dimensions?** Reflection in 3 dimensions refers to the transformation of a point, line, shape, or object in a three-dimensional space across a plane or an axis.

**What are 3 examples of real reflection?** Three examples of real reflections are:

- Looking at your reflection in a mirror.
- Seeing your reflection on the surface of still water.
- Light reflecting off a smooth surface, such as glass.

**How do you calculate mirror reflection?** To calculate mirror reflection, you need to know the original coordinates of a point or object and apply the reflection rules to find the new reflected coordinates.

**Is mirror formula important?** Yes, the mirror formula is important in optics as it relates the object distance, image distance, and focal length of a mirror, which is crucial in understanding image formation by mirrors.

**Which mirror is negative?** A concave mirror is considered negative because its focal length is negative. In the mirror formula, if the focal length (f) is negative, it indicates a concave mirror.

**What is the angle of reflection 45?** If the angle of incidence is 45 degrees, according to the law of reflection, the angle of reflection will also be 45 degrees.

**What if the angle of reflection is 60?** If the angle of incidence is 60 degrees, according to the law of reflection, the angle of reflection will also be 60 degrees.

**Is the angle of reflection always 90 degrees?** No, the angle of reflection is not always 90 degrees. It is equal to the angle of incidence only when light reflects off a flat surface, such as a mirror. In other cases, it depends on the angle at which the light strikes the surface.
