MHT CET Physics question
On investigation of light from three different stars A, B and C it was found that in the spectrum of A, the intensity of red colour is maximum, in B, the intensity of blue colour is maximum and in C the intensity of yellow colour is maximum. From the observation it can be concluded that
Answer: (C)
Solution
Peak wavelength falls as temperature rises (red > yellow > blue in wavelength), so blue-peaked B is hottest, yellow-peaked C
