Question

Which statements describe diffraction? Check all that apply.

Answer 1

Answer: Diffraction occurs when waves interact with a gap.

Diffraction occurs in any type of wave—mechanical or electromagnetic.

Explanation:

The phenomenon of light to bend around a small obstruction in its path is known as diffraction. Diffraction occurs for any type of waves- transverse or longitudinal i.e. for mechanical or electromagnetic waves.

When the medium changes- refraction occurs. Waves reflect back from a barrier. Diffraction occurs when the wavelength of the wave is comparable to the size of the gap. The wave bends around the corners of the gap.

Answer 2

-- Diffraction occurs when waves interact with a barrier.
-- Diffraction occurs when waves interact with a gap.
-- Diffraction occurs in either type of wave—mechanical or electromagnetic.
