Sound Assessment Pilot @ IKE 24-25

Front

What is a transverse wave?

Back

A wave created by shaking a rope up and down, where the motion of the medium is perpendicular to the direction of the wave.

Front

What unit is used to measure loudness?

Back

A decibel (dB).

Front

What property of a wave controls its pitch?

Back

Frequency.

Front

What happens when you pluck a guitar string?

Back

The string vibrates.

Front

In a standing wave, what are nodes?

Back

Points where the wave has minimum amplitude and does not move.

Front

In a standing wave, what are antinodes?

Back

Points where the wave has maximum amplitude and vibrates the most.

Front

How many nodes are present in a standing wave with 4 nodes?

Back

4 nodes.

Front

How many antinodes are present in a standing wave with 3 antinodes?

Back

3 antinodes.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the medium moves perpendicular to the wave direction; in longitudinal waves, the medium moves parallel to the wave direction.
