Intensity of x-rays coming from an x-ray tube is plotted against wavelength as shown:-

Options

A. (a) If accelerating potential is changed keeping target same, then sharp peaks `(lambda_(2) & lambda_(3))` will shift to new position.
B. (b) If accelerating potential is changed keeping the target same, then minimum wavelength of spectrum `(lambda_(1)) ` will shift to new location
C. (c) In the radiation coming out of the tube photons corresponding to wavelength `lambda_(3)` will have more energy than those corresponding to `lambda_(2)`
D. (d) In the radiation coming out of the tube number of photons corresponding to wavelength `lambda_(3)` will be more in number than number of photons corresponding to `lambda_(2)`

Answer

B, D

Explanation

Spectrum peaks are due to characterstic X-rays, which depend on target, where as `lambda_(min)` is a property of accelerating voltage.
