When a light comes from an optically denser substance to an optically less dense substance, the ray is refracted1 pointtowards the normalout of the normaldoes not recract at all

Memory rule: A light ray travels through an optically denser substance1 pointcloser to the normalfurther from the normal

What happens to light as it enters an optically less dense medium at an angle?A) It speeds up and bends away from the normal.B) It slows down and bends towards the normal.C) It speeds up and bends towards the normal.D) It slows down and bends away from the normal.

563%Substance 1 has a refractive index of 1.7 and substance 2 has a refractive index of 1.2. Light passes from substance 1 into substance 2. Will it bend towards or away from the normal?

If a ray of light in a glass is incident on an air surface at an angle greater thanthecritical angle, the ray will:A. Refract only B. Reflect onlyC. Partially reflect & refract D. Diffract only

Part C: When light passes through a denser medium, how does the wavelength affect the angle of refraction?
