Polarisation

Polarization is a process that makes transverse waves, like light, oscillate in one plane. It is used to detect stress lines in transparent materials and create 3D effects. Unlike transverse waves, longitudinal waves, such as sound, cannot be polarized as they oscillate in the direction of motion.

What is the primary characteristic of a transverse wave that allows it to be polarized?

• It travels faster than sound.

• It oscillates in one plane only.

• It requires a medium to travel.

• It oscillates in multiple planes.

Which of the following is a common use of polarization?

• Reducing wave amplitude

• Increasing wave speed

• Creating 3D visual effects

• Enhancing sound quality

How does polarization help in material science?

• By increasing material strength

• By revealing hidden stress lines

• By reducing material density

• By changing material color

Why can't longitudinal waves be polarized?

• They are too fast to be polarized.

• They oscillate in the direction of motion.

• They require a vacuum to travel.

• They oscillate in multiple directions.

Which type of wave is sound classified as?

• Transverse wave

• Longitudinal wave

• Surface wave

• Electromagnetic wave
