21. What is an example of a concave function? An example of a concave function is the quadratic function �(�)=−�2f(x)=−x2. It has a downward-facing parabolic shape and a concave down graph.

22. What are the 4 types of concave? There are not four types of concave, but rather concave refers to the shape of mirrors or lenses. Concave mirrors and concave lenses are the two main types based on their shape.

23. What is an example of a concave surface? An example of a concave surface is the inner surface of a bowl or a cave’s interior walls. These surfaces curve inward.

24. Does a concave mirror have a surface? Yes, a concave mirror has two surfaces: a reflective surface on the inside (concave side) and a non-reflective surface on the outside.

25. What is an example of a concave down equation? An example of a concave down equation is the quadratic function �(�)=−�2f(x)=−x2, which has a downward-facing parabolic shape.

26. What is the concavity theorem? The concavity theorem is a mathematical concept used in calculus. It states that if the second derivative of a function is positive, the function is concave up; if the second derivative is negative, the function is concave down.

27. Is concavity the second derivative? Yes, concavity is determined by the second derivative of a function. If the second derivative is positive, the function is concave up, and if it’s negative, the function is concave down.

31. What is a concave length of focal length? The concave length of focal length is not a standard term. The focal length of a concave mirror is typically denoted by “f.”

32. What is the position of a concave mirror between C and f? When a concave mirror is positioned between its center of curvature (C) and its focal point (f), it forms a real and inverted image beyond the center of curvature.

33. What is the object at C in a concave mirror? When the object is placed at the center of curvature (C) of a concave mirror, the image is also formed at the center of curvature, and it is real, inverted, and the same size as the object.

34. What is the image formed by a concave mirror at the focus? If an object is placed at infinity in front of a concave mirror, the image will be formed at the focus (f). The image will be real and highly focused.

37. How do you find the nature of an object in a concave mirror? To determine the nature of an object in a concave mirror, consider its position relative to the focal point (f) and the center of curvature (C). If it is beyond C, the image is real and inverted; if between C and f, the image is real and inverted but smaller; if at f, there is no real image; if between the mirror and f, the image is virtual and upright.

38. When the distance of an object from a concave mirror is? This question seems incomplete. Please provide more details for a specific question.

39. What is the distance between object and image in a concave mirror? The distance between the object and the image in a concave mirror depends on the specific positions of the object and image. It can be calculated using the mirror equation.

42. Does a concave mirror make things bigger or smaller? A concave mirror can make things either bigger or smaller depending on the object’s position relative to the mirror. If the object is beyond the focal point, the image will be smaller; if it’s between the focal point and the mirror, the image will be larger.
