Question 3

What is the formula for wave speed?

Accepted Answer

Frequency × Wavelength

Answer

Mass ÷ Volume

Answer

Voltage × Current

Answer

Acceleration × Time

Question 4

What is the difference between amplitude and wavelength?

Accepted Answer

Amplitude is the maximum displacement from rest position, while wavelength is the distance between two consecutive crests or troughs.

Answer

Amplitude is the distance between two consecutive crests or troughs, while wavelength is the maximum displacement from rest position.

Answer

Amplitude is the distance between two points on a wave, while wavelength is the time it takes for one wave cycle to be completed.

Answer

Amplitude and wavelength are the same thing.

Question 5

What is the unit of frequency?

Accepted Answer

Hertz

Answer

Watt

Answer

Ohm

Answer

Second

Question 6

What is the relationship between frequency and wavelength?

Accepted Answer

They are inversely proportional.

Answer

They are directly proportional.

Answer

They are not related.

Answer

It depends on the type of wave.

Question 7

What is the speed of sound in air?

Accepted Answer

343 m/s

Answer

0 m/s

Answer

299,792,458 m/s

Answer

9.81 m/s²

Question 8

What is the difference between transverse and longitudinal waves?

Accepted Answer

Transverse waves vibrate perpendicular to the direction of wave propagation, while longitudinal waves vibrate parallel to the direction of wave propagation.

Answer

Transverse waves vibrate parallel to the direction of wave propagation, while longitudinal waves vibrate perpendicular to the direction of wave propagation.

Answer

Transverse waves have higher frequency than longitudinal waves.

Answer

Transverse waves cannot travel through a vacuum.
