Physical Science Chapter 8: (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 factors affect the speed of a wave?

Back

The speed of a wave depends on the medium through which it travels, such as air, water, or solid materials.

Front

What is frequency?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as from 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 wave's energy.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a standing wave?

Back

A standing wave is a wave that remains in a constant position, characterized by nodes (points of no movement) and antinodes (points of maximum movement).

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another due to a change in speed.

Front

What is reflection?

Back

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