What represents the colour of star-
Text Solution
Verified by ExpertsThe correct answer is:
D
According to weins displacement law 
constant or temperature 
It represents that greater the temperature T of an emitted star, smaller the value of wave length 
.
We also know the wave length of ray depends upon its colour. Hence, when the temperature of star increases, the wave length of star decreases. When temperature of star decreases, the wave length increases and star moves towards the red colour. Therefore, the colour of star indicates its temperature.
