If 20 sound waves pass through a point in a medium in 2 s with the velocity of 20 m/s, then thewavelength will be
Question
Solution
To find the wavelength, we first need to find the frequency of the wave. Frequency is defined as the number of waves passing through a point in a certain amount of time.
Step 1: Calculate the frequency Frequency = Number of waves / Time Frequency = 20 waves / 2 s = 10 Hz
The velocity of a wave is given by the equation: Velocity = Frequency * Wavelength
Step 2: Solve the above equation for Wavelength Wavelength = Velocity / Frequency Wavelength = 20 m/s / 10 Hz = 2 m
So, the wavelength of the sound wave is 2 meters.
