The speed limit for a vehicle on road is 120 km/ hr. A policeman detects a drop of 10% in the pitch of horn of a car as it passes him. Is the policeman justified in punishing the car driver for crossing the speed limit? (Given: Velocity of sound= 340 m/s)
Let velocity of a sound wave be 'v' and 'ω' be angular velocity. The propagation constant of the wave is .................................
If the difference in velocities of light in glass and water is 2.7 x 107 m/s, find the velocity of light in air. (Refractive index of glass = 1.5, Refractive index of water = 1.333)
