Waves Questions and Answers Part-7

1.Water waves are
a) Longitudinal
b) Transverse
c) Both longitudinal and transverse
d) Neither longitudinal nor transverse

Answer: c
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

Answer: c
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

Answer: a
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

Answer: d
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

Answer: a
Explanation: Wave on a plucked string is stationary wave. Light waves are EM waves. Water waves are transverse as well as longitudinal.

Answer: b
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

Answer: b
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

Answer: d
Explanation: Sound wave in a gas
