Optics Prism desperately need help optics question?
Light is incident on an equilateral glass prism at a 45.0 degree angle to one face. Calculate the angle at which light emerges from the opposite face. Assume that n=1.58.
Equilateral glass prism of 60 degrees between the glass surface.
So at 45.0 degree incidence on one glass surface, using sin 45 / sin r = 1.58, r = 26.6 degrees. This ray will hit at the second surface at an incident angle of 33.4 degrees. But at the 2nd surface, this light will bend away from the normal, since it is travelling from glass into air.
so at the second glass-air boundary,
sin i(the angle in air) / sin 33.4 = 1.58
i = 60.5 degrees. (the angle which emerge at the 2nd surface)
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of 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 are not in fact in the shape of geometric prisms. Prisms are typically made out of glass, but can be made from any material that is transparent to the wavelengths for which they are designed. A prism can be used to break light up into its constituent spectral colors (the colors of the rainbow). Prisms can also be used to reflect light, or to split light into components with different polarizations. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

High Quality Content by WIKIPEDIA articles In geometry, the octagonal prism is the sixth in an infinite set of prisms, formed by square sides and two regular octagon caps. If faces are all regular, it is a semiregular polyhedron. In optics, octagonal prisms are used to generate flickerfree images in movie projectors. It is also an element of two fourdimensional uniform polychora: the omnitruncated tesseract and runcitruncated tesseract. A right prism is a prism in which the joining edges and faces are perpendicular to the base faces. This applies if the joining faces are rectangular. If the joining edges and faces are not perpendicular to the base faces, it is called an oblique prism. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

optics !!!!!!!!!!!!!!!!!!!!!!!!!!!?
a thin prism of angle 5 degrees is placed at a distance of 10 cm from object. What is the distance of the image from the object ? (given refractive index of prism=1.5)
Hello Mukhul, the question is so abstract and ambiguous. Please give it in the right sense.
