If the frequency of an emitted x-ray is 1.6 x 10\(^{16}\)Hz, the accelerating potential is?

[e = 1.6 x 10\(^{-19}\)J, h = 6.63 x 10-\(^{34}\)Js]

Given f = 1.6 x10\(^{16}\)H\(_{3}\), h = 6.63 x 10\(^{-39}\)Js

e = 1.6 x 10\(^{-19}\)C, V = ?

V = \(\frac{w}{e} = \frac{hf}{e}\) = \(\frac{1.6 \times 10^{16} \times 6.63 \times 10^{34}}{1.6 \times 10^{-19}}\)

= 66.3V
