The effect of the angle for a particular order or constructive interference from a crystal, when the photon energy of an x-ray beam is increasing.
Answer to Problem 1CQ
Explanation of Solution
Given info: The photon energy of an x-ray beam is increasing.
Explanation:
Write the expression for the Bragg condition.
Here,
Write the expression for the energy of the x ray crystal.
Here,
When the energy of the photon increase, the wavelength of the photon will decrease.
From the Bragg condition, the wavelength of the photon is related to the angle of incidence
Therefore, the angle for a particular order or constructive interference from the crystal decreases, when the photon energy of an x-ray beam increases.
Conclusion:
Therefore, the angle for a particular order or constructive interference from the crystal decreases, when the photon energy of an x-ray beam increases.
