Question

a) Write the rules of refraction.
b) The refractive index depends on
what.​

Answer 1

Answer:

• The incident ray refracted ray, and the normal at the point of incidence all lie on the same plane

• The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.

                             sin i / sin r = constant

b]  Refractive Index of a medium depends upon the optical, density, the wavelength of the light, and speed of light
