Question

The minimum wavelength of the X-rays produced by electrons accelerated through a potential difference of V volts is directly proportional to (A) (1/√ V) (B) (1/V) (C) √ V (D) V2

Tardigrade Admin · Accepted Answer

By the law of photo-electric effect (hc/λ)=eV or λ=(hc/eV) propto (1/V)

Q. The minimum wavelength of the X-rays produced by electrons accelerated through a potential difference of $V$ volts is directly proportional to

$\frac{1}{V}$

$\frac{1}{V}$

$V$

$V^{2}$

By the law of photo-electric effect $\frac{h c}{λ} = e V$
or $λ = \frac{h c}{e V} \propto \frac{1}{V}$

Q. The minimum wavelength of the X-rays produced by electrons accelerated through a potential difference of V volts is directly proportional to

V​1​

V1​

V​

V2

By the law of photo-electric effect λhc​=eV or λ=eVhc​∝V1​
