Polarisation

Og-1 Polarisation

Published: Wednesday 15 March 2006

To demonstrate various aspects of polarised light.

Og-2 Strain Polarisation

Published: Wednesday 15 March 2006

To demonstrate strain birefringence.

Og-3 Interference colours in Mica (Polarisation)

Published: Wednesday 15 March 2006

To demonstrate interference colours in mica sheet.

Og-4 Polarisation by Scattering

Published: Wednesday 15 March 2006

To demonstrate that scattered light is polarised. When the direction of observation is normal to the primary beam, the light is completely linearly polarized.

Og-5 The Barbers Pole (optical Activity)

Published: Wednesday 15 March 2006

To demonstrate that the rotation of the plane of polarisation in a sugar solution ((optical activity) is wavelength dependent.

Og-6 Voice Communication Using a Laser Beam (The Faraday Effect)

Published: Wednesday 15 March 2006

To demonstrate the transmission of sound via the modulation of a laser beam using the Faraday effect.
