Question

1. Which one of the following statements regarding wavelength is correct?

A) Wavelength is the distance between two consecutive locations where the medium is at equilibrium.

B) Wavelength is the distance from a crest to the next trough.

C) Wavelength is the distance that the wave travels in a time of one period

2) If the tension in a guitar string is increased, what happens to the speed of a wave in the string?
a) The wave speed decreases.

b) The wave speed is unchanged.

c) The wave speed increases.

(1)

The wavelength in a longitudinal wave is the distance between two consecutive points that are in phase.

option (A) is correct answer

option (B) is wrong because the distance between crest to the next trough is half wavelength.

option (C) is correct answer

(B)

speed of transverse wave in a guitar string is

v= sqrt T/ u

speed of wave is directily proportional to sqaure root of tension

when tension in a guitar string is increased ,The wave speed increases.

so option (c) is correct answer
