Find the frequency & wavelength of a wave whose time period is 0.05 sec & speed is 200 m/s.

Step 1: Find the Frequency

The frequency of a wave can be calculated using the formula:

Frequency (f) = 1 / Time period (T)

Given that the time period (T) is 0.05 seconds, we can substitute this into the formula:

Frequency (f) = 1 / 0.05 = 20 Hz

So, the frequency of the wave is 20 Hz.

Step 2: Find the Wavelength

The wavelength of a wave can be calculated using the formula:

Wavelength (λ) = Speed (v) / Frequency (f)

Given that the speed (v) is 200 m/s and the frequency (f) we calculated is 20 Hz, we can substitute these into the formula:

Wavelength (λ) = 200 / 20 = 10 m

So, the wavelength of the wave is 10 meters.
