Waves Unit Review

Front

What are the three types of mediums through which waves can travel?

Back

Solid, Liquid, or Gas

Front

In a wave diagram, how can you identify the wave with the greatest wavelength?

Back

The wave with the longest distance between consecutive peaks or troughs has the greatest wavelength.

Front

What is the term for the change in direction of a ray of light when it hits a surface?

Back

Reflection

Front

Why do we hear thunder after seeing lightning?

Back

Because light travels faster than sound.

Front

What is the relationship between wavelength and energy in waves?

Back

Longer wavelengths correspond to lower energy.

Front

Define a wave in the context of physics.

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What is the difference between mechanical and electromagnetic waves?

Back

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

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (or about 300,000 kilometers per second).

Front

What is refraction in the context of waves?

Back

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

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.
