Question
Download Solution PDFWhen a beam of ordinary light is passed through a calcite crystal, the light splits into O-ray and E-ray inside the crystal.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFWhen ordinary light is allowed to pass through calcite or quartz, it splits into two refracted beams(O-ray & E –ray) and both are plane-polarized lights.
Polarisation:
- The phenomenon due to which vibrations of light waves are restricted in a particular plane is called polarisation.
- In an ordinary beam of light from a source, the vibrations occur normal to the direction of propagation in all possible planes. Such a beam of light called unpolarised light.
- If by some methods (reflection, refraction, or scattering) a beam of light is produced in which vibrations are confined to only one plane, then it is called plane polarised light.
- Hence, polarization is the phenomenon of producing plane polarised light from unpolarised light.
Additional Information
There are three types of polarized light
- Plane Polarized Light
- Circularly Polarized Light (O-ray)
- Elliptically Polarized Light (E-ray)
