प्रश्न
State three factors on which the angle of deviation depends.
उत्तर
The value of the angle of deviation (or the deviation produced by a prism) depends on the following four factors:
- the angle of incidence (i),
- the material of the prism (i.e., on refractive index μ),
- the angle of prism (A),
- the colour or wavelength (λ) of light used.
