The radiation emitted by the surface of the Sun emits maximum power at a wavelength of about 500 n m . Assuming the Sun to be a blackbody emitter. If its surface temperature K is given by α ∙ β × 10 γ then fill the value of α + β + γ . (Wien’s constant is given by 2.898 m m K )
Correct answer
16
Step-by-step solution
λ = 500 nm , T = b λ T = 2 .898   mm 500   nm = 5 .8 × 10 3
