Wave Properties
Waves is cause by vibrations or oscillations.
Can either be a Mechanical waves which
require a medium to travel eg. Sound wave
or Electromagnetic waves which do not
require a medium to travel.
- 1.
Figure A :The vibration of the particles of the medium is ____________ to the motion of the wave.
Explanation
Oscillations of transverse waves are at right angles to direction of motionRate this question:
- 2.
Which of the following is true?
- A.
The direction of propagation of longitudinal wave is perpendicular to the direction of vibration of particles.
- B.
An example of transverse wave is sound wave.
- C.
The direction of propagation of transverse wave is perpendicular to the direction of vibration of particles.
Correct Answer
C. The direction of propagation of transverse wave is perpendicular to the direction of vibration of particles.Explanation
sound wave is a longitudinal wave.Rate this question:

The diagram shows ripples produced by a vibrating spherical dipper. classify point P.Q,R,S,T, and U into two groups that formed specified wavefronts.
- A.
P, Q, Rand S,T,U
- B.
P,Q T and R, S, U
- C.
P,T,U and Q, S, R
Correct Answer
C. P,T,U and Q, S, RExplanation
The sets of P,T, U and Q,S, R forms to different imaginary line joining points which are in phase and have the same distance from the source.Rate this question:

Which of the following is true?
- A.
The direction of wave propagation is perpendicular to the wavefront.
- B.
The direction of wave propagation is parallel to the wavefront.
- C.
The direction of wave propagation is in the opposite direction of the wavefront.
Correct Answer
A. The direction of wave propagation is perpendicular to the wavefront.Explanation
The direction of wave propagation is always perpendicular to the wavefront.Rate this question:

The diagram shows a tranverse wave. The amplitude and wavelength are represented by...
- A.
Amplitude - RS ; Wavelength - PQ
- B.
Amplitude - Op ; Wavelength - RP
- C.
Amplitude - RP ; Wavelength - OQ
- D.
Amplitude - OQ ; Wavelength - PS
Correct Answer
C. Amplitude - RP ; Wavelength - OQExplanation
RP is the amplitude that is the distance from the equilibrium position to the maximum displacement.
OQ is the wavelength that is the distance between two points that are in phase.Rate this question:

The diagram shows three compression areas of a slinky spring. What is the wavelength?
- A.
1 cm
- B.
3 cm
- C.
6 cm
- D.
12 cm
Correct Answer
B. 3 cmExplanation
for a longitudinal wave, wavelength can be measured from a compression to the next consecutive compression region. The arrow shows the length of 2 wavelengths.Rate this question:
