Questions + Answers key
Take MCQ Physics Test1.
Write down the factors affecting velocity of sound in gases.
2.
The speed of a wave in a certain medium is 900 m/s. If 3000 waves passes over a certain point of the medium in 2 minutes, then compute its wavelength?
3.
Why is it that transverse waves cannot be produced in a gas? Can the transverse waves can be produced insolids and liquids?
4.
A sound source and listener are both stationary and a strong wind is blowing. Is there a Doppler effect?
5.
How do animals sense impending danger of hurricane?
1.
(i) Pressure
(ii) Temperature
(iii) Density
(iv) humidity and
(v) wind
2.
Given:
Speed v = 900 m / s
In 120 s number of waves produced =3000
In 1 s number of waves produced
\(f=\frac{3000}{120}=25 \mathrm{~Hz}\)
We know that
Wavelength \(\lambda=\frac{v}{f} \)
\(\lambda=\frac{900}{25}=36 \mathrm{~m}\)
3.
Transverse waves travel in the form of crests and troughs and so involve change in shape. Transverse waves can be produced in a medium which has elasticity in shape. As gas has no elasticity of shape, hence transverse wave cannot be produced in a gas. Transverse waves can be produced in solids and on the surface of liquids.
4.
When both source and listener are stationary there is no relative motion between the source and the observer. Hence there is no Doppler effect.
5.
Hurricane produces a shock wave which has a speed greater than the speed of sound. If travels with a supersonic sound that can be easily sensed by animals, using Doppler effect, The multiple reflections of sound can be easily sensed by animals.
