Waves Practice

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, which determines the volume of the sound.

Front

What is frequency in wave terminology?

Back

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

Front

What does wavelength refer to in waves?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement above the rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the maximum displacement below the rest position.

Front

What does the term 'wave propagation' mean?

Back

Wave propagation refers to the movement of waves through a medium, indicating how energy is transferred from one point to another.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the oscillation is parallel to the direction of wave propagation (e.g., sound waves), while in transverse waves, the oscillation is perpendicular to the direction of wave propagation (e.g., light waves).

Front

What is resonance in the context of waves?

Back

Resonance occurs when an object vibrates at its natural frequency due to an external force, leading to an increase in amplitude.

Front

How does changing the amplitude affect sound?

Back

Changing the amplitude of a sound wave affects its volume; a larger amplitude results in a louder sound.
