Question

Select the appropriate unit for each type of measurement.
Amplitude: meters, decibels, hertz, or meters/seconds
Frequency: meters, decibels, hertz, or meters/seconds
Wavelength: meters, decibels, hertz, or meters/seconds
Wave speed: meters, decibels, hertz, or meters/seconds
Loudness: meters, decibels, hertz, or meters/seconds

Answer 1

Amplitude: Meters/seconds
Frequency: Hertz
Wavelength: meters
Wave speed: meters/seconds
Loudness: decibels

Answer 2

Answer:

Amplitude: Meters

Frequency: Hertz

Wavelength: meters

Wave speed: Meters/second

Loudness: decibels

• Explanation:

• Amplitude is defined as the distance from mean position of the wave to the center of crest or trough. The S.I. unit for this is meters.

• Frequency is defined as the number of oscillations happening in one second. It is measured in Hertz.

• Wavelength is defined as the distance between two crests or two troughs. It is a measured in meters.

• Wave speed is defined as the number of waves happening in 1 second. Hence, the unit to measure this property is meters/second.

• Loudness of a sound is the measurement which determines the sound. Its unit is decibels.

Hence, Units of

Amplitude : Meters

Frequency : Hertz

Wavelength: meters

Wave speed: Meters/second

Loudness: decibels
