A sound wave vibrates with a frequency of 318 Hz. What is the speed of sound if the wavelength is 0.896 m?

A. 2790 m/s
B. 36.3 m/s
C. 355 m/s
D. 285 m/s

Answer :

The speed of sound can reach 285 metres per second. option.D

The formula for calculating the speed of sound is:

Frequency x Wavelength = Speed

The frequency of the sound wave in this case is 318 Hz, and the wavelength is 0.896 m. As a result, the speed of sound can be estimated as follows:

318 Hz x 0.896 m = speed

285 m/s is the maximum speed.

The wave's amplitude is not required to compute the speed of sound. The highest displacement of the wave from its equilibrium position is referred to as amplitude, and it has no effect on the wave's speed.

It should be noted that the speed of sound is affected by the qualities of the medium through which it travels.The speed of sound in air at room temperature is roughly 343 m/s, however it varies depending on temperature, pressure, and humidity.

The speed of sound can be substantially faster in other medium, such as water or steel. As a result, the given frequency and wavelength correspond to different sound velocity in different mediums.So Option D is correct.
