## Question

### Solution

Correct option is

None of these

The equation of a plane progressive wave moving in the +X direction is given by

Where is the amplitude, T is the time-period and λ is the wavelength. Here a = 0.07 m, n = 400 Hz (s –1) and wave-speed v = 300 m/s.

Substituting these values of aT and λ in the above equation, we get
