Wave Reflection, Refraction & Interference in Technology

Front

What is the definition of diffraction?

Back

Diffraction is the spreading out of waves as they pass through an opening or around objects.

Front

According to the Law of Reflection, what happens to a light ray striking a mirror?

Back

A light ray striking a mirror bounces off the mirror at the same angle it hits.

Front

What type of wave interaction occurs when waves spread out after passing through an opening?

Back

Diffraction.

How do noise-canceling headphones utilize wave interference?

Back

Noise-canceling headphones use destructive interference to cancel out unwanted noise.

Front

If a reflected wave bounces off a mirror at an angle of 65 degrees, what is the angle of incidence?

Back

The angle of incidence is also 65 degrees.

Front

What is the principle behind wave reflection?

Back

The principle of wave reflection states that the angle of incidence is equal to the angle of reflection.

Front

Define refraction in the context of wave behavior.

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is constructive interference in wave interactions?

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference in wave interactions?

Back

Destructive interference occurs when two waves meet and combine to form a wave with a smaller amplitude or cancel each other out.

How does the speed of light change when it enters a denser medium?

Back

The speed of light decreases when it enters a denser medium.
