Properties and Behavior of Waves

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, caused by a change in its speed.

Front

What are the highest points of a transverse wave called?

Back

Crests are the highest points of a transverse wave.

Front

What are the lowest points of a transverse wave called?

Back

Troughs are the lowest points of a transverse wave.

Front

What is amplitude in relation to waves?

Back

Amplitude is the maximum distance that the wave moves from its rest position; it is related to the energy carried by the wave.

Front

How does amplitude affect wave energy?

Back

The bigger the amplitude, the more energy is carried by the wave.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in a given period of time, usually measured in Hertz (Hz).

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is 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 motion of the medium is parallel to the direction of the wave's travel.

Front

What is reflection in wave behavior?

Back

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