Question

If 20 waves pass through a medium in 1 second with a speed of 20 meter per second then the wavelength is.

Answer 1

Answer:

20 waves per second. Frequency is 20/s. Speed is 20m/s. V = wavelength * freq 20m/s = w * 20/s Wavelength = 1 meter.

Answer 2

Given that 20 waves pass through a medium in 1 second.

Frequency(f) = 20 m/sec

Given speed(v) is 20 m/sec.

We need to find the wavelength.

What is wavelength?

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in consecutive cycles.

Now,

Wave equation

$v = f \lambda\\\Rightarrow \lambda = \frac{v}{f}\\\Rightarrow \lambda = \frac{20}{20}\\\Rightarrow \lambda = 1 \ m/sec$

Therefore, the wavelength is 1 m/sec.
