Wave Review 2024

Front

What is reflection in terms of wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a surface that it cannot pass through.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, due to a change in its speed.

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to an external force.

Front

What is the best material for reflecting light waves?

Back

Mirrors are the best materials for reflecting light waves.

Front

How does a prism separate white light?

Back

A prism separates white light through refraction, bending different wavelengths of light at different angles.

Front

Why do we see objects as white?

Back

We see objects as white because they reflect all wavelengths of visible light.

Front

What happens to light when it is absorbed by an object?

Back

When light is absorbed by an object, it does not reflect back, and the object may appear darker.

Front

What is the difference between transmission and absorption of light?

Back

Transmission is when light passes through an object, while absorption is when light is taken in by the object.

Front

What is the law of reflection?

Back

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