Waves and Wave Properties - Pretest

Front

What is Reflection in terms of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier or surface.

Front

What is Refraction in terms of waves?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is Absorption in terms of waves?

Back

Absorption is the process by which a wave's energy is taken in by a material, converting it to other forms of energy.

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum because it requires a medium (solid, liquid, or gas) to propagate.

Front

Which type of light has the lowest energy: Radio, Microwave, Infrared, or Ultraviolet?

Back

Radio waves have the lowest energy among these types of light.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium) and electromagnetic waves (which do not require a medium).

Front

What is the wavelength of a wave?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz).
