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

Answer: C - Light from the Sun reflecting off the moon bends around particles in Earth's atmosphere and then spreads out.

Explanation:

Diffraction is a phenomena where in light bends around the corners of obstacle in its path. This happens when the size of the obstacle is comparable to the wavelength of the light.

Moon does not have its own light. It reflects the sunlight which is received by us. The light after reflection from the surface of the moon passes through the atmosphere of Earth before we perceive it. Thus, the light bends around the corners of the particles in the atmosphere and spreads out. This causes the fuzzy glow around a full moon.

the answer is C., ...
