Light and Sound Waves

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 light waves?

Back

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

Front

What are sound waves?

Back

Sound waves are mechanical waves that require a medium (like air, water, or solids) to travel.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs of a wave.

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position to its crest or trough.

Front

What is frequency?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is reflection?

Back

Reflection is the bouncing back of a wave when it hits a surface that does not absorb the wave's energy.

Front

What is refraction?

Back

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

Front

What is a plain mirror?

Back

A plain mirror is a flat surface that reflects light, allowing us to see our image.
