प्रश्न
The given graph (Fig.12.2) shows the displacement versus time relation for a disturbance travelling with a velocity of 1500 ms–1. Calculate the wavelength of the disturbance.
उत्तर
From the given graph,
The time period of the disturbance,
T = 2 µ s = 2 × 10−6s
Velocity of disturbance, v = 1500 ms_l So, wavelength of the disturbance,
λ = vT
= 1500 m s−1 × 2 × 10−6 s
= 3 × 10−3 m
