Plane harmonic waves of frequency 500 Hz are produced in air with displacement amplitude 1 x 10-3 cm. Deduce energy flux in J/m2) in the wave (density of air =1.29 gm/lit, speed of sound in air = 340 m/s).


Detailed Solution for Waves NAT Level - 1 - Question 1


The correct answer is: 0.22

Plane harmonic waves of frequency 500 Hz are produced in air with displacement amplitude 1 x 10-3 cm.  Deduce pressure amplitude (in N/m2).  (density of air = 1.29 gm/lit, speed of sound in air = 340m/s)


Detailed Solution for Waves NAT Level - 1 - Question 2

Given A = 1 x 10-3 cm = 10-5 m, v = 500 Hz, v = 340 m/s, p = 1.29 g/lit = 1.29 kg/m3
Pressure amplitude

= 2 x 3.14 x 10-5 x 500 x 340 x 1.29
= 13.8 N/m2 
The correct answer is: 13.8

If the frequency of a tuning fork is 400 Hz and the velocity of sound in air is 320 m/s, find how far does the sound travel (in m) while the fork completes 30 vibrations?


Detailed Solution for Waves NAT Level - 1 - Question 3


∴ Distance travelled by the wave when the fork completes 1 vibration = 0.8 m.
So distance travelled by the wave when the fork completes 30 vibrations.
= 0.8 x 30
= 24m
The correct answer is: 24

The vibrations of a string of length 60 cm fixed at both ends are represented by the equation

where x and y are in cm and t in seconds. What is the maximum displacement of point x = 5cm ?

Detailed Solution for Waves NAT Level - 1 - Question 4

The given equation is :

This can be written as :

This shows that a = 2 cm, λ =30 cm and ω = 1440 cm/s
The maximum displacement is given by :

For x = 5 cm

The correct answer is: 3.464

A transverse harmonic wave of amplitude 0.02 m is generated at one end (x = 0) along horizontal string by a tuning fork of frequency 500 Hz. At a given instant of time, the displacement of the particle at x = 0.1 m is 0.005 m and that of the particle at x = 0.2 m is 0.005 m. Calculate the wavelength of the wave?

Detailed Solution for Waves NAT Level - 1 - Question 5

The general equation of this wave is given by

Here A = 0.02 m
Again, when x = 0.1m, y = -0.005 m

or


Again x = 0.2m, y = 0.005m





or λ = 0.2m
The correct answer is: 0.2
