Questions
What is the approximate surface temperature of red star?
a
4114 K
b
5226 K
c
7420 K
d
6821 K
detailed solution
Correct option is A
Maximum radiation from the surface of star takes place for the wavelength of red light i.e. for λ=7000A0Now λT=0.288K−cm⇒T=0.2887000×10−8K=4114KTalk to our academic expert!
