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

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
