DOUBLE REFRACTION OR BIREFRINGENCE • When ordinary light is allowed to pass through a calcite or quartz, it splits into two refracted beams (O . Light - Light - Reflection and refraction: Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray.
A ray of nm light goes from air into fused quartz at an incident angle of º. At what incident angle must nm light enter flint glass to have the same angle of refraction? A narrow beam of light containing red ( nm) and blue ( nm) wavelengths travels from air through a cm thick flat piece of crown glass and back to air again. When a ray of light strikes a mirror perpendicular to its surface, the angle of reflection is (A) 0° (C) 60° (B) 45° (D) 90° Parallel light rays are incident on the surface of a plane mirror. Upon reflection from the mirror the light rays will (A) converge (C) be parallel (B) diverge (D) be scattered A light ray is incident upon. (c) We conclude that white light is polychromatic in nature. MULTIPLE CHOICE TYPE. Question: 1. When a white light ray falls on a prism, the ray at its first surface suffers: (a) no refraction (b) only dispersion (c) only deviation (d) both deviation and dispersion. Solution. A monochromatic ray of light PO is incident at the face of the prism A. Complete the diagram to show the path of the ray till it emerges out of the prism B. Answer: See figure. Question Draw a diagram to show the refraction of a monochromatic light ray through an equilateral prism. On the diagram, label the incident, refracted and emergent.
Double Refraction. When unpolarised light is incident on a calcite or quartz crystal it splits up into two refracted rays. one of which follows laws of refraction. called ordinary ray (O-ray) and other do not follow laws of refraction. called extraordinary ray (E-ray). This phenomena is called double refraction. The actual division of a light ray into two visible species, each refracting at a different angle, is the process of double refraction. In contrast, birefringence refers to the physical origin of the separation, which is the existence of a variation in refractive index that is sensitive to direction in a geometrically ordered material. Double Refraction When unpolarised light is incident on a calcite or quartz crystal it splits up into two refracted rays. one of which follows laws of refraction. called ordinary ray (O-ray) and other do not follow laws of refraction. called extraordinary ray (E-ray). This phenomena is called double refraction. This condition is known as birefringence. Polarized light microscopy produces images by utilizing the interference of the split light rays as they re-assemble along the same optical path. The split rays travel at different speeds through the specimen and one ray is retarded with respect to the other. This optical condition is known as retardation.
