Question

For harder X-rays,
(a) the wavelength is higher
(b) the intensity is higher
(c) the frequency is higher
(d) the photon energy is higher.

Answer 1

For harder X-rays

(d) the photon energy is higher

Explanation:

Hard x rays

• They are less wavelength, energy is high at the electromagnetic spectrum.
• The energy of gamma rays are high.
• Hard x rays are higher energy.
• Soft x rays are lower energy.
• The energies more than 10KeV are x rays harder.
• Soft x rays can penetrate less in a substance than X rays harder, required denser and detected large massive material.
• The reflection is difficult in x rays. X-rays wavelength on the sequence or less than the size of atom.
• The waves can reflect when they appeared less and photon particles are more that they pass through the atoms.
• Before interacting they penetrate the material with an individual atom.

Answer 2

For harder ex-rays, the photon energy and the frequency is higher. So, the answers are (c) and (d).

EXPLANATION:

• Harder x-rays are the ones that have lesser wavelengths. Hard x-rays have higher frequency since the frequency differs with the wavelength inversely.  
• The photon energy is shown as E. E = hcλ  
• where,
• c = light’s speed
• h = Constant of Planck  
• λ = Light’s wavelength  
• Obviously, with wavelength, energy varies inversely. So, the photon’s energy will be greater for the hard X-ray.
