# X-Ray Interference Pattern

APPH12-ZE@BK@

Students are experimenting with low energy x-rays that carry a quantum energy of $124\text{ eV}$. They have a diffraction grating with a spacing of $2000$ lines per centimeter.

What change could you suggest to solve their dilemma?

A

Make the room darker, the light in the room is masking the pattern of the x rays.

B

Use a diffraction grating with a spacing that has more lines per centimeter.

C

Increase the intensity of the x-rays to make the pattern more prominent.

D

Move the receiver closer to the grating to allow distance for the intensity of the beam to decrease according to the inverse square law of light intensity.
