The surface temperature of the stars is ...

The surface temperature of the stars is determined using

A

distance

B

colour

C

size

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
We know from Wien's displacement law that
`lambda_(m)T=b, ` where
`lambda_(m)`=wavelenght of light emitted with maximum intensity.
T=Temperature of the star
`therefore ` From the colour (wavelength) of the emitted light, we can determine the temperature of the star.
