1.Water waves are
a) Longitudinal
b) Transverse
c) Both longitudinal and transverse
d) Neither longitudinal nor transverse
Explanation: Water waves are transverse as well as longitudinal in nature.
2. Sound travels in rocks in the form of
a) Longitudinal elastic waves only
b) Transverse elastic waves only
c) Both longitudinal and transverse elastic waves
d)Non-elastic waves
Explanation: Both longitudinal and transverse elastic waves
3.The waves in which the particles of the medium
vibrate in a direction perpendicular to the
direction of wave motion is known as
a) Transverse wave
b) Longitudinal waves
c) Propagated waves
d) None of these
Explanation: In transverse waves medium particles vibrate perpendicular to the direction of propagation of wave.
4. A medium can carry a longitudinal wave because
it has the property of
a) Mass
b) Density
c) Compressibility
d) Elasticity
Explanation: Elasticity
5. Which of the following is the longitudinal wave
a) Sound waves
b) Waves on plucked
string
c) Water waves
d) Light waves
Explanation: Wave on a plucked string is stationary wave. Light waves are EM waves. Water waves are transverse as well as longitudinal.
6. The nature of sound waves in gases is
a) Transverse
b) Longitudinal
c) Stationary
d) Electromagnetic
Explanation: Longitudinal
7. Transverse waves can propagate in
a) Liquids
b) Solids
c) Gases
d) None of these
Explanation: Transverse wave can propagate in solids but not in liquids and gases.
8.Sound waves in air are
a) Transverse
b) Longitudinal
c) De-Broglie waves
d) All the above
Explanation: Because sound waves in gases are longitudinal.
9.Which of the following is not the transverse wave
a) X-rays
b) \[\gamma -rays\]
c) Visible light wave
d) Sound wave in a gas
Explanation: Sound wave in a gas
10.What is the phase difference between two
successive crests in the wave
a) \[\pi\]
b) \[\pi/2\]
c) \[2 \pi\]
d) \[4 \pi\]
Explanation: Since distance between two consecutive crests
