Edexcel A-Level Physics AS 2.3.49 Plane Polarisation Questions

Practise Edexcel A-Level Physics plane polarisation with filters, rotating planes, transverse-wave evidence and stress-pattern observations.

Exam points

identify that only transverse waves can be plane polarised in multiple-choice contexts
describe laser or lamp-filter demonstrations using rotation and observed intensity changes
explain stress patterns from crossed polarisers, plane rotation and bright or dark regions

[Maximum number: 2]

Light is a transverse wave.

The light emerging from prism B is observed through a polarising filter. The polarising filter is rotated gradually, and the light transmitted by the filter varies in intensity.

Explain how this observation demonstrates that light waves are transverse.
