3. Transverse and Longitudinal Waves

Question 1

What is a Transverse wave?

Answer 1

A transverse wave is a wave that displaces particles at right angles to the direction of energy propagation

Question 2

What is a Longitudinal wave?

Answer 2

A longitudinal wave is where the wave that displaces particles along the direction of energy propagation

Question 3

What is a Polarised wave?

Answer 3

A polarised wave is a wave that is only travelling in a certain direction

Question 4

What causes a polarised wave to form?

Answer 4

putting a wave through a polarising filter will make a polarised wave

Question 5
