Questions + Answers key
Take MCQ Physics Test1.
What is Echo?
2.
What is the effect of pressure on velocity of sound in gas?
3.
Define amplitude of the wave.
4.
Give the relation between velocity v, angular frequency \(\omega\) and wave number \(\lambda\)?
5.
Define frequency and time period.
1.
An echo is a repetition of sound produced by the reflection of sound waves from a wall, mountain or other obstructing surfaces.
2.
For a fixed temperature, when the pressure varies, correspondingly density also varies such that the ratio \((\frac{p}{\rho})\) becomes constant. This means that the speed of sound is independent of pressure for a fixed temperature.
3.
An amplitude of the wave is defined as the maximum displacement of the medium with respect to a reference axis (for example in this case x-axis). Here, it is denoted by A.
4.
Velocity, v = \(\lambda f\frac{\lambda}{2\pi}(2\pi f)=\frac{2\pi f}{2\pi /\lambda}=\omega/k\)
5.
Frequency is defined as "the number of waves crossing a point per second" It is measured in hertz.
Frequency and time period are inversely related i.e.,
\(T=\frac{1}{f}\)
Time period is defined as the time taken by one wave to cross a point.
