Question 1
The direction of vibration in a longitudinal wave is:
- Aat right angles to the wave direction
- Bin circular motion
- Copposite to the wave direction
- Din the same direction as the wave travels
Show answerHide answer
Answer: D
In longitudinal waves the particles vibrate parallel to the direction in which the wave is travelling.
Question 2
Which part of a transverse wave carry the lowest point?
- ACrest
- BCompression
- CRarefaction
- DTrough
Show answerHide answer
Answer: D
The trough is the region of a transverse wave below the mean position, the lower part of a wave.
Question 3
Which of the following wave type requires a medium to travel?
- AX-rays
- BLight waves
- CRadiowaves
- DSound waves
Show answerHide answer
Answer: D
Sound waves are mechanical waves; X-rays, light waves and radiowaves are electromagnetic waves and need no medium.
Question 4
The property of a wave which indicates how much energy it carries is:
- Acrest
- Bamplitude
- Cwavelength
- Dspeed
Show answerHide answer
Answer: B
The amplitude indicates the energy carried by the wave.
Question 5
A wave front is:
- Athe distance between two crests
- Ba region of high pressure in a wave
- Ca line joining points that vibrate in phase
- Dthe outer edge of a wave medium
Show answerHide answer
Answer: C
A wave front is an imaginary surface on which all the points have the same phase of vibration.
