The minimum wavelength of X -rays produced by an electron accelerated through a potential difference of   V volts is proportional to:

Options

  1. AV 2
  2. BV
  3. C1 V
  4. D1 V

Correct answer

C. 1 V

Step-by-step solution

Minimum wavelength means maximum energy as E = h c λ . Therefore, e V = h c λ m i n ⇒ λ m i n = h c e V ⇒ λ m i n ∝ 1 V
