Question 1
Polarization of light shows that light waves are:
- ALongitudinal
- BTransverse
- CStationary
- DMechanical only
Show answerHide answer
Answer: B
Only transverse waves can be polarized so polarization proves light is transverse.
Question 2
Polarization does not occur in:
- ALight waves
- BTransverse waves on a string
- CSound waves
- DElectromagnetic waves
Show answerHide answer
Answer: C
Sound waves are longitudinal and cannot be polarized.
Question 3
In a transverse wave the vibrations of the particles are:
- AParallel to the direction of propagation
- BPerpendicular to the direction of propagation
- CAbsent
- DAlong the wave energy flow only
Show answerHide answer
Answer: B
Transverse vibrations are at right angles to the direction of propagation.
Question 4
The plane of polarization is the plane containing:
- AThe direction of vibration only
- BThe direction of propagation only
- CThe direction of vibration and the direction of propagation
- DThe magnetic field only
Show answerHide answer
Answer: C
It contains both the vibration direction and the propagation direction.
Question 5
A light wave consists of oscillating:
- AElectric field E only
- BMagnetic field B only
- CElectric field E with magnetic field B at right angles to it
- DSound pressure
Show answerHide answer
Answer: C
Light is an electromagnetic wave with E and B perpendicular to each other.
