00:50 Questions for Short Answer :Wave Motion and Waves on a String From Question 1 To 8
Que.1 You are walking along a seashore and a mild wind is blowing. Is the motion of air a wave motion ?
Que. 2 The radio and TV programmes, telecast at the studio, reach our antenna by wave motion. Is it a mechanical wave or nonmechani‘al ?
Que. 3 A wave is represented by an equation y = c1 sin (c2x + c30. In which direction is the wave going ? Assume that c1, c2 and c3 are all positive.
Que. 4 Show that the particle speed can never be equal to the wave speed in a sine wave if the amplitude is less than wavelength divided by 2Tt.
Que. 5 Two wave pulses identical buted with respect to each other are produced at the two ends of a stretched string. At an instant when the pulses reach the middle, the string becomes completely straight. What happens to the energy of the two pulses?
