FAQs

1. What is the formula for magnitude to flux conversion?
   • Estimation: The formula to convert apparent magnitude to flux is approximately F = 2.512^(-m), where “m” is the apparent magnitude.
2. Is flux equal to apparent magnitude?
   • Estimation: No, flux and apparent magnitude are not equal. They are related, but flux is a quantitative measure of energy or particles per unit area, while apparent magnitude is a measure of the brightness of a celestial object as seen from Earth.
3. What is the conversion of flux?
   • Estimation: Flux conversion depends on the context. It can refer to converting from one flux unit to another or from apparent magnitude to flux using the formula mentioned earlier.
4. How do you convert counts to flux?
   • Estimation: Converting counts to flux depends on the specific measurement and instrument used. Typically, it involves calibrating the instrument to relate counts to a known flux of particles or energy.
5. What is the relation between magnitude and flux?
   • Estimation: The relation between magnitude and flux is an inverse exponential relationship, as described by the formula F = 2.512^(-m), where “m” is the apparent magnitude.
6. Is flux the same as absolute magnitude?
   • Estimation: No, flux is not the same as absolute magnitude. Absolute magnitude is a measure of an object’s intrinsic brightness, while flux is a measure of the amount of energy or particles received per unit area.
7. How do you convert apparent magnitude to absolute magnitude?
   • Estimation: To convert apparent magnitude to absolute magnitude, you need the object’s distance. The formula is often M = m – 5 * log10(d) + 5, where “M” is the absolute magnitude, “m” is the apparent magnitude, and “d” is the distance in parsecs.
8. What is apparent flux?
   • Estimation: Apparent flux is not a standard term. It may refer to the measured flux of an object as observed from a specific location, taking into account factors like distance and extinction.
9. What is apparent magnitude?
   • Estimation: Apparent magnitude is a measure of the brightness of a celestial object as seen from Earth. It quantifies how bright an object appears in the sky.
10. What is the general formula for flux?
    • Estimation: The general formula for flux in physics is Φ = E * A * cos(θ), where Φ is the flux, E is the field’s strength, A is the area through which the field passes, and θ is the angle between the field and the normal to the area.

22. Why is apparent magnitude negative?
    • Estimation: Apparent magnitudes can be negative for objects that appear fainter than the reference stars used to establish the magnitude scale. Negative values indicate dimmer objects.
23. How are absolute magnitude and apparent magnitude similar?
    • Estimation: Both absolute magnitude and apparent magnitude are measures of an object’s brightness, but they differ in that apparent magnitude depends on the observer’s location and distance, while absolute magnitude is an intrinsic property.
