A sound’s loudness is measured in decibels (dB). Therefore option 1 can’t be the unit of frequency of a sound wave. The loudness of sound is determined by the intensity of the sound waves.
Read moreWhat is s-1 for frequency?
Frequency’s units are per second, written s-1 or hertz, Hz. Hertz and per second are identical units, i.e. 1 s-1 = 1 Hz . When describing a moving wave, frequency means the number of peaks which pass a stationary point in a given amount of time.

The frequency SI unit is the hertz (Hz) . One hertz is the same as one per second cycle.
Read moreWhat is the CGS and SI unit of frequency?
In CGS system, unit of frequency is denoted by Hertz or Hz . CGS system is also defined as the Centimetre gram second system which is the smaller unit than the SI system. One Hertz denote the one cycle per second.
Read moreWhat are the units for frequency?
The SI unit for frequency is the hertz (Hz) . One hertz is the same as one cycle per second.
Read moreHow does period relate to frequency?
More formally, the frequency is inversely proportional to the period. If you double the period, the frequency is halved.
