The diagram alongside shows the refraction of a ray of light from air to a liquid.
(a) Write the values of (i) angle ofincidence, and (ii) angle of refraction.
(b) Use Snell's law to find the refractive index of liquid with respect to air.
the refractive index of water for light going from air to water is 1.33. find the refractive index of air for a beam of light going from water to air.
