Dual Nature of Radiation and Matter – Solutions

1) Find the

(a) Maximum frequency, and

(b) Minimum wavelength of X-rays produced by 30 kV electrons.

Solution:

According to the given data,

Energy, E = eV

E = 30 x 1.6 x 10^-19 J

E = 4.8 x 10^-15 J

(a) Maximum frequency:

Since, E =hv = hc/λ [where h = plank’s constant, v =frequency, λ = wavelength]

v = E/h
