Diffraction

Question 6 • Crowley Credit Recovery Physics B

What causes diffraction that results in a fuzzy glow around a full moon?

Answer
A
Moonlight converges into a single area around the moon called a shadow region.
B
Moonlight bends toward a single area around the moon called a shadow region.
C
Light from the Sun reflecting off the moon bends around particles in Earth’s atmosphere and then spreads out.
D
Light from the Sun reflecting off the moon then reflects off particles in Earth’s atmosphere and scatters.

Explanation

Diffraction occurs when light bends around small objects or particles and spreads out. The Moon shines by reflecting sunlight, and particles in Earth’s atmosphere can cause this bending and spreading, creating a fuzzy glow. Choice D describes reflection and scattering, not diffraction.
