Q. The difference between soft and hard X-rays is of

Rajasthan PMTRajasthan PMT 2007Dual Nature of Radiation and Matter

Solution:

The penetrating power of $ X- $ rays depends upon their wavelength, which depends upon frequency.
The frequency of the longer wavelength $ X- $ rays is lower and so their energy is smaller. Hence, their penetrating power is weaker and they are called soft $ X- $ rays. While the penetrating power of the shorter wavelength $ X- $ rays is stronger and they are called hard or highly penetrating $ X- $ rays.
