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
EXAMPLES: (i) A book lying on the table remains at rest until it is listed or pushed by exerting a force. (ii)A rolling ball on the ground comes to rest after covering some
Velocity: It is common to find people confusing the terms velocity and speed when describing how fast an object is moving. The difference is that speed is a scalar quantit
