What happens to o-ray and e-ray if they travel along the optic axis
Answers
Answer:
Explanation:
Lets discuss 'The mechanism of light splitting in a calcite crystal' to understand the consequences for o-ray and e-ray when they travel along the optic axis:
=> An anisotropic medium, A calcite in which when light enters it break up into two half. It is known as double refraction or Birefringences.
=> The light which enters is mostly unpolarised light when it enters in crystal and after coming out of it from other end it becomes polarised. ..
=> Calcite should have an optical axis where there is no refraction. But after partition, they travel in two directions.
=> The ray which diverges from its own path which is known as e-ray and the other which does not change the path is o ray.
=> These both e-rays and O rays travels in different direction and their plane of vibration is also perpendicular against each other.
=> The vibration of O rays is perpendicular to the plane of paper, but with its paper or sheet or mobile plane in the e-ray.
=> In addition, the refractive index (a number that decides the particular bending angle for every medium) of the ordinary ray Is seen constant in all directions;
=> Refractive index of extraordinary ray varies according to direction as it contains elements that are parallel as well as vertical of crystal optic axis.
=> Since, the speed of light waves in a wave and in a vacuum is equal to each other, it divided by the index of refraction for that wavelength, an extraordinary ray appears to be moving at slow speed as compared to the O- ray.
