Question
200 waves pass through a point in one second. Calculate the time period of wave.
Advertisements
Solution
Waves passing through a point in 1 second = 200
We know, frequency (ƒ) = Number of waves passing through a point in 1 second.
∴ ƒ = 200Hz
Also, T = `1/"f"`
∴ Time period (T) = `1/200`
T = 0.005s
