Prism Different Angle
Product Code : EL-LAO-10338
Quick answer: The Prism Different Angle is used in school and college optics to study refraction and dispersion of light and to show how the deviation of a ray depends on the refracting angle of a prism, through the pin method on a drawing board or on a spectrometer. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
When light passes through a prism it bends towards the base at both faces, and the total deviation depends on the angle of incidence, the refractive index of the material and the refracting angle A of the prism. At minimum deviation Dm the refractive index is mu = sin((A + Dm)/2) / sin(A/2), and for a thin prism the deviation is approximately (mu - 1)A, so a larger prism angle gives a larger deviation.
Comparing prisms of different refracting angles lets students test this directly: with the same material and the same light, the prism with the greater angle turns the ray further and spreads white light into a wider spectrum.
- Place the prism on a sheet of paper on a drawing board and trace its outline.
- Fix two pins as the incident ray and view their images through the other face, fixing two more pins in line with them.
- Join the pin marks to draw the incident and emergent rays and measure the angle of deviation.
- Repeat for several angles of incidence and plot deviation against incidence to find the minimum deviation.
- Repeat with a prism of a different angle and compare the results.

Frequently asked questions
How does the angle of a prism affect deviation?
For the same material and light, a larger refracting angle gives a larger deviation; for a thin prism the deviation is approximately (mu - 1)A.
Which prism experiment is done in school physics?
Tracing the path of a ray through a prism by the pin method and plotting the angle of deviation against the angle of incidence to find the angle of minimum deviation.
