Draw a ray diagram to show the refraction of a monochromatic ray through a prism when it suffers minimum deviation.
State the dependence of angle of deviation on the refractive index of the material of the prism.
Draw diagrams to show the refraction of light from
- air to glass, and
- glass to air. In each diagram, label the incident ray, refracted ray, the angle of incidence
- and the angle of refraction (r).
A ray of light of wavelength 6600 Å suffer refraction from air to glass. Taking \[\ce{_a\mu_g = \frac{3}{2}}\], find the wavelength of light in glass.
