Question

33. Velocity of wave along a straight depends upon
(A) T and m
(B) Length, thickness
(C) both (a) and (b)
(D) None of these​

Answer 1

Answer:

The speed of a wave on a string depends on the linear density of the string and the tension in the string. The linear density is mass per unit length of the string. In general, the speed of a wave depends on the square root of the ratio of the elastic property to the inertial property of the medium.

Answer 2

Answer:

the right answer is -(C) both a and b
