Waves and Wave Interactions

Front

What is the difference between sound waves and light waves in terms of speed?

Back

Sound waves are the FASTEST in solids (high density), while light waves are the FASTEST in gas (or no molecules).

Front

Why can you see an explosion in space but not hear it?

Back

Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.

Front

What happens to waves when they encounter rough surfaces?

Back

Waves are absorbed.

Front

What happens to light when it hits a dark colored shirt?

Back

Light is absorbed.

Front

What type of waves do not require a medium to travel?

Back

Electromagnetic waves.

Front

Define mechanical waves.

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium.

Front

Give an example of a mechanical wave.

Back

Sound waves are an example of mechanical waves.

Front

What is reflection in terms of wave behavior?

Back

Reflection is when a wave bounces off a surface.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another.
