2. the direction perpendicular to the direction of wave

3. the direction diagonal to the direction of wave

4. a direction that cannot be predicted

Q. Which of the following statements are correct regarding longitudinal waves?

1. Compressions and rarefactions are formed
2. Particles oscillate about their mean positions
3. Particles oscillate perpendicular to the direction of wave propagation
4. Particle oscillate parallel to the direction of wave propagation

Q. Explain the propagation of sound in solids. [3 Mark]

Q. If a longitudinal wave is travelling in the west direction, what can be the possible direction of the vibration of particles of the medium?

1. East-west
2. Up-down
3. North-south
4. Medium needs to be specified

Q. Question 2

1. True
2. False

Q. Light wave is an example of a wave.

1. mechanical
2. non-mechanical
3. longitudinal

Q.

Particles in a longitudinal wave move perpendicular to the direction of the wave propagation.

1. True

2. False

Q. Which of these is not an example of mechanical wave?

1. Sound waves
2. Seismic waves
3. Light waves
4. Water waves

Q. In a longitudinal wave, particles vibrate ______ the direction of the propogation of the wave.

1. along
2. perpendicular to
3. independent of
4. oblique to

Q. Which type of waves can propagate in solids?

1. Both transverse and longitudinal
2. Transverse
3. Neither transverse nor longitudinal
4. Longitudinal

Q. For a sound wave travelling from east to west, the particles vibrate in ___ direction.

1. north-south
2. east-west
3. north east- south west
4. up-down

Q.

Look at the following figure and choose the correct statement regarding sound propagation in this case.

1. Sound travels as both transverse and longitudinal waves.

2. Sound travels only as a longitudinal wave.

3. Sound does not travel as sound requires air as a medium for its propagation.

4. Sound travels only as a transverse wave.

Q.

1. True

2. False

Q. Which among the following statements is true?

2. Sound cannot propagate in outer space.
3. Sound moves very slowly in the outer space.
4. Intensity of sound gets reduced in the outer space.
