The velocity of sound in any gas depends upon
1 wavelength of sound
2 density and elasticity of gas
3 intensity of sound waves
4 amplitude and frequency of sound
Explanation:
B We know that, velocity of sound $(v)=\sqrt{K / \rho}$ where $\mathrm{K}=$ The modulus of bulk elasticity for gases and $\rho=$ density of the medium So velocity of sound depends upon both density and elasticity of gas.

Which one of the following statements is true?
1 Both light and sound waves in air are transverse
2 The sound waves in air are longitudinal while the light waves are transverse
3 Both light and sound waves in air are longitudinal
4 Both light and sound waves can travel in vacuum
Explanation:
B Transverse wave: Transverse waves are waves in which the direction of vibration of particle in a medium perpendicular to the direction of propagation the wave. Ex: Light wave and all electromagnetic waves. Longitudinal waves: Longitudinal waves are waves in which the direction of vibration of particles in a medium is along the direction of propagation of the wave Ex. sound wave.

Given that $y=A \sin \left[\left(\frac{2 \pi}{\lambda}(\operatorname{ct}-x)\right)\right]$, where $y$ and $x$ are measured in metre. Which of the following statements is true?
1 The unit of $\lambda$ is same as that of $x$ and $A$

Explanation:
A Given that $y=A \sin \left[\left(\frac{2 \pi}{\lambda}(c t-x)\right)\right]$ Thus dimensions of $\lambda$ must be same as dimensions of $\mathrm{x}$ and $\mathrm{A}$. Its dimension is [L]

For a wave propagating a medium, identify the property that is independent of the others.
1 velocity
2 wavelength
3 frequency
4 all these depend on each other
Explanation:
C We know that, $\text { v }=\mathrm{f} \lambda$ $\text { Where, }$ $\text { v, velocity }$ $\text { f, frequency }$ $\lambda \text {, wavelength }$ Any medium has its characteristic such as refractive index which affects the characteristics of a wave such as wavelength, velocity etc. Frequency is also a characteristic of a wave. The velocity and wavelength of a wave decrease by a factor $m$ (refractive index) on passing through a medium but frequency remains unchanged. Hence, it is independent of medium.
