Compton effect supports that
If a photon has velocity $c$ and frequency $\nu$, then which of following represents its wavelength
What is velocity of photon ?
Specific heat of water is $4.2 \,J / g ^{\circ} C$. If light of frequency $3 \times 10^9 \,Hz$ is used to heat $400 \,gm$ of water from $20^{\circ} C$ to $40^{\circ} C$, the number of photons needed will be
