Question

What is the formula of speed of wave ?​

Answer 1

Answer:

Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.

Answer 2

Speed = Wavelength x Frequency.

v the velocity of the wave

f frequency of the wave

\lambda. wavelength.

Solved Example

: A sound wave has a wavelength of 1.5 mm, then find out its frequency.

Solution:

Given:

Wavelength, \lambda = 1.5 mm,

Speed of sound, v = 343.2 m/s.

The frequency is:

f = \frac{v}{\lambda }\\

f = \frac{343.2}{ 1.5 × 10^-^2}

= 22.8 KHz.

The frequency of the sound waves is 22.8 kHz.
