Mechanical Waves Review

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position. It is a measure of the wave's energy.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation. They consist of compressions and rarefactions.

Front

What is frequency in the context of waves?

Back

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

Front

What is the relationship between frequency and pitch?

Back

Higher frequency waves produce higher pitch sounds, while lower frequency waves produce lower pitch sounds.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and the spreading out of waves when they pass through small openings.

Front

What are crests and troughs?

Back

Crests are the highest points of a wave, while troughs are the lowest points.

Front

What is the difference between compression and rarefaction?

Back

Compression is a region in a longitudinal wave where particles are close together, while rarefaction is a region where particles are spread apart.

Front

How does amplitude affect sound?

Back

Amplitude affects the loudness of a sound; greater amplitude results in louder sounds.

Front

What is reflection in wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a barrier, such as sound waves reflecting off walls.

Front

What is interference in waves?

Back

Interference occurs when two or more waves overlap and combine to form a new wave pattern.
