Waves CP Unit Test 24 25

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 wavelength?

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 amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

How do sound waves travel?

Back

Sound waves travel through the vibration of particles in a medium, such as air, water, or solids.

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves carry more energy than lower frequency waves.

Front

What is the speed of light compared to the speed of sound?

Back

Light travels much faster than sound; in a vacuum, light travels at approximately 299,792 kilometers per second, while sound travels at about 343 meters per second in air.

Front

What happens to the energy of a wave as its amplitude increases?

Back

As the amplitude of a wave increases, the energy of the wave also increases.

Front

What is a sound wave's lowest energy point?

Back

The lowest energy point in a sound wave is represented by the lowest amplitude.

Front

How do you measure the amplitude of a wave?

Back

To measure the amplitude of a wave, you measure the distance from the rest position to the crest or trough.
