Waves and Wave Properties - Pretest

Front

What is Reflection in the context of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier or surface. For example, when light hits a mirror, it reflects back.

What is Refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, caused by a change in speed. For example, a straw in a glass of water appears bent due to refraction.

What is Absorption in wave properties?

Back

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

Which type of light has the lowest energy?

Back

Radio waves have the lowest energy compared to microwaves, infrared, and ultraviolet light.

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

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, like sound waves) and electromagnetic waves (which do not require a medium, like light waves).

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle movement is perpendicular to the direction of wave travel (e.g., light waves). In longitudinal waves, the particle movement is parallel to the direction of wave travel (e.g., sound waves).

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means more waves in a given time.
