Polarisation

Question 1

Polarisers

Answer 1

• Only allow transverse waves at particular angles to pass through

Question 2

Polarisers at right angle

Answer 2

• If two polarisers were placed at right angles to each other, no light would pass through
• First, the polariser would only transmit horizontally polarised light
• The second polariser can only transmit vertically polarised light
• The incoming horizontally polarized light would be completely absorbed by the second polariser
