About black body radiation, which one of the following is a WRONG statement? (a) For all wavelengths, power radiated is same (b) For shorter wavelengths, radiated power is more (c) for longer wavelengths, radiated power is less (d) All wavelengths are emitted by the black body

Answer: (a). A black body emits all wavelengths, but the power radiated is different at different wavelengths, with a peak at λm. So 'power radiated is same for all wavelengths' is false. So the wrong statement is (a).

About black body radiation, which one of the following is a WRONG statement?

Show answer and solution

Answer: (a)

A black body emits all wavelengths, but the power radiated is different at different wavelengths, with a peak at $\lambda_m$ .
So 'power radiated is same for all wavelengths' is false.
So the wrong statement is (a).
