Imagine a ray of light passing between air (n~1) and glass (n~1.5). If the ray of light hits the glass from the air at an angle of 60 degrees, what will the new angle of the light be relative to that air-glass interface as it travels through the glass? (Hint: Remember that you need to focus on the angle of the light relative to a line perpendicular to the air-glass interface when using Snell's Law)
Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
