From the graph we get,

Time-period, T = 2 * 10^-6s.

Frequency is the number of wave cycles or revolutions per second. The formula for period (T) in terms of frequency is given by:

Frequency, √ = = 5 * 10⁵ Hz.

Wavelength Formula for any wave is given by:

Wavelength, λ =

Velocity of the wave = 1500 ms^-1

Therefore, λ = 1500 * 2 * 10^–6

= 3 * 10³ * 10^-6

= 3 * 10^-3 m
