Both the strings, shown in figure (15.Q1), are made of same material and have same cross section. The pulleys are light. The wave speed of a transverse wave in the string AB is υ₁ and in CD it is υ₂. Then υ₁/υ₂ is

A cork floating in a calm pond executes simple harmonic motion of frequency v when a wave generated by a boat passes by it. The frequency of the wave is

Two string A and B, made of same material, are stretched by same tension. The radius of string A is double of the radius of B. A transverse wave travels on A with speed υ_A and on B with speed υ_B. The ratio υ_A/υ_B is

Velocity of sound in air is 332 m s⁻¹. Its velocity in vacuum will be

A wave pulse, travelling on a two-piece string, gets partially reflected are partially transmitted at the junction. The reflection wave is inverted in shape as compared to the incident one. If the incident wave has wavelength λ and the transmitted wave λ’,
