i want the readings for dependence of angle of deviation on the angle of incidence by using a hollow prism filled one by one with water,kerosene oil & turpentile oil

INTRODUCTION:
In the prism of a transparent optical element with flat, polished surfaces That refract light.The exact angles between surfaces depends on the application.TheTraditionalgeometrical form a triangular prism with a triangular base and rectangular sides, and in colloquial use "Prism" usually refers to this type. Some types of optical Prism has Notin factor in the form of geometric prisms.Prisms can be any material made from this istransparent wavelengths for which they are intended. Typical materials include glass, plastic, and fluoride. You CAN BYT′A prism to break the light into constituent spectral colors (color therainbow) STI. The Prism can be used to reflect light, or to split Light into components withdifferent polarization.

THEORY:

Refraction:

In a homogeneous environment, light travels in a straight line, but when it falls on a surface of a different environment, a very small part of it is reflected back and most of the world runs on Wednesday, though with a change of direction. This phenomenon is the bending of light on the surface section of the two mediums is called refraction of light.


Causes refraction:

The phenomenon of refraction is kakwhen when a beam of light enters the environment in which the light enters the environment in which light travels at different speeds.

Laws of refraction:

1. Ray, refracted and the surface normal at point fall on the same plane.
2. for any given section of the two media, relevant personality from the angle of incidence the angle of refraction is a constant, where is the angle of incidence and the angle of refraction.
Average: The Next A substance through which the light passes.
For monochromatic light, the ratio of the angle of incidence of the angle of refraction is a constant for any given section of the two media. If ' I ' is the angle of incidence, and the ' g ' is the angle of refraction, then;

The constant is called the refractive index. In most cases, it can be assumed that the refractive index of air.

When the software update via OTA less light passes the denser medium, it bends the opposite Kthe normal iwhen when she goes out more dense to sparse environment. Experiments show that

Through Prism refraction:

AProzračnaâ environment is limited to two flat surface are inclined to each other at an angle, is called Prism. The angle between the two surfaces is known as the angle of the Prism.

[C1] angle: the angle at which the incident beam of light is called the skew angle. In fact it is the angle between the beam and the resulting incident Ray Produced.

The angle of minimum deviation: the value of the angle of incidence (1) increases, the angle decreases to a value for the angle of incidence, it reaches a minimum value, a minimum deviation angle, m is called.


Critical angle:

This is what the angle in a dense environment, for which the angle of refraction in a rare environment is 90 degrees.

TheČetyre setting angle depends on The:

1. Angle Prism (A)
2. material of a Prism (m)
3. angle of incidence (I)
4. the wavelength or color of light (l)


Refraction through a Prism:

The theory relation from the perspective of:

When a beam of light passes from one medium to another, he either goes to normal or from normal in the second environment, depending on the second Wednesday of more dense or less in relation to the first environment. This phenomenon is known as refraction of light.

For a given pair of two mediums, as well as to a specific wavelength of light (color) the ratio of the angle of incidence and the angle of refraction is a constant value called the refractive index of the second medium relative to the environment. She is represented by:

Thus, the magnitude of the angle I can be obtained in terms of angle of the Prism and refracting angle and the minimum deviation angle of refraction r t and can also be obtained from the point of view of angle and prisms refracted
Let ABC represent a cross section of a glass Prism and let Bud′tea IP beam falling at an angle I do on first AB prisms at the point p. N1PN is normal to do so.
