Light Waves and Sound Waves Review

Front

What is refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, changing speed.

Front

What is reflection?

Back

Reflection is the bouncing back of light waves when they hit a surface.

Front

Which wave has the greatest frequency in a diagram?

Back

The wave with the shortest wavelength has the greatest frequency.

Front

What are mechanical waves?

Back

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

Front

What is a medium in the context of waves?

Back

A medium is the material through which a wave travels.

Front

What type of waves do not require a medium?

Back

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

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the shortest wavelength and highest frequency.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength decreases, frequency increases.

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 (km/s).

Front

What is the difference between sound waves and light waves?

Back

Sound waves are mechanical waves that require a medium, while light waves are electromagnetic waves that can travel through a vacuum.
