A black body has maximum wavelength

\lambda m

at temperature 2000 K. Its corresponding wavelength at temperature 3000 K will be

View answer and explanation

Correct option: B

\frac{2}{3}{\lambda _m}

Option D (

\frac{T}{8}

) is correct because the potential energy is half of the total energy at

t = \frac{T}{8}

in simple harmonic motion.
