A) velocity
B) intensity
C) frequency
D) polarization
Correct Answer: C
Solution :
Fact: The x-rays which are less penetrating known as soft x-rays, The penetrating power of x-rays depends upon their wavelengths which depends upon frequency. The frequency of the longer wavelength x-ray is lower and so, their energy is smaller. Hence, their penetrating power is weaker and they are called soft x-rays. On the other hand the penetrating power of the shorter wavelength x-rays is stronger and the penetrating power of shorter wavelength x-rays is stronger and they are called hard or highly penetrating x-rays.
