Question

An x-ray photon of initial frequency 3.0 x 10^19 Hz collides with an electron and is scattered through 90°. Its new frequency will be... * A. 2.4x10^19 Hz. B. 2.6x10^19 Hz. C. 2.5x10^19 Hz. D. 3.2x10^19 Hz

Answer 1

The new frequency of the scattered photon will be the same as the initial frequency of 3.0 x 10^19 Hz.

Step-by-step explanation:

When an x-ray photon collides with an electron and is scattered through 90°, its new frequency can be determined using the conservation of energy and momentum. In this case, the energy of the photon and electron before and after the collision remains the same. Therefore, the new frequency of the scattered photon will be the same as the initial frequency of 3.0 x 10^19 Hz.

Answer 2

option D. The new frequency of the scattered X-ray photon will be 3.0 x 10^19 Hz.

Step-by-step explanation:

To determine the new frequency of the scattered X-ray photon, we can use the principle of conservation of energy.

Since the collision is elastic, the total energy before and after the collision should remain the same.

Therefore, the new frequency will be 3.0 x 10^19 Hz.
