The ratio of kinetic energy of the particle to the energy of the photon is : (velocity of light is 3×10^8m/s)

The de-Broglie wavelength of a particle moving with a velocity 2.25×10^8 m/s is equal to the wavelength of photon. The ratio of kinetic energy of the particle to the energy of the photon is : (velocity of light is 3×10^8m/s)

Light of wavelength λ falls on a metal having work function hc/ λ0. Photoelectric effect will take place only if
