Text Solution

Verified by Experts
The correct answer is:
C

-ray beam comming from tube, contain more than one wavelength. Hence, not monochromatic.

Let the potential difference between accelerating plates of tube

Maximum craned by electron

This maximum is equal to maximum energy of -Ray of photon

X-ray beam has energy less than or equal to Hence wavelength is greater than or equal to
