Waves

Front

What are compressions in a longitudinal wave?

Back

Compressions are the parts of a longitudinal wave where the coils are close together.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, not bouncing back.

Front

What type of waves require a medium to pass?

Back

Mechanical Waves require a medium (like air, water, or solid materials) to travel.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a type of wave that can travel through both matter and empty space.

Front

What happens when light hits an area and bounces back?

Back

This process is called reflection.

Front

What are rarefactions in a longitudinal wave?

Back

Rarefactions are the parts of a longitudinal wave where the coils are spread apart.

Front

What is the difference between mechanical waves and electromagnetic waves?

Back

Mechanical waves need a medium to travel, while electromagnetic waves do not.

Front

Can sound waves travel through a vacuum?

Back

No, sound waves are mechanical waves and require a medium to travel.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

What is the principle of reflection?

Back

The principle of reflection states that when a wave hits a surface, it bounces back at the same angle.
