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.
