Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength.
Work function W = hγo = h C / λ 0
λ 0 = h C / W
= 6.626 X 10-34 X 3 X 10 8 / 1.8 X 1.6 X 10 -19
= (19.878 / 2.88) X 10-7 m
= 6.902 X 10-7 m
Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
Photoelectric effect An effect described by A. Einstein that demonstrates that light appears to be built up of photons or particles. Light can do excite electrons (called phot
