	The momentum of a photon of energy $h\nu $will be
	A photon in motion has a mass
	If the momentum of a photon is p, then its frequency is (Where m is the rest mass of the photon)
	An AIR station is broadcasting the waves of wavelength 300 metres. If the radiating power of the transmitter is 10 kW, then the number of photons radiated per second is
	The energy of a photon is $E = hv$ and the momentum of photon $p = \frac{h}{\lambda }$, then the velocity of photon will be
	The approximate wavelength of a photon of energy 2.48 eV is
	An important spectral emission line has a wavelength of 21 cm. The corresponding photon energy is
	The momentum of a photon in an X-ray beam of ${10^{ - 10}}$metre wavelength is
	The energy of a photon of light with wavelength 5000 Å is approximately 2.5 eV. This way the energy of an X-ray photon with wavelength 1Å would be
