Refraction in lenses

When a ray of light passes through a transparent object such as a block of glass, it refracts twice. Once when it enters the glass and once again when it exits. In order to trace the complete path a ray of light takes, both these points of refraction need to be considered separately.

Light Reflection and Refraction

Light is a complex phenomena. It exhibits both wave

Specular vs Diffuse Reflection

Our ability to see and make sense of the world with our eyes depends on the reflective properties of light. Without reflection, we would only see luminous objects like the sun, light bulbs, and computer screens.

The light rays that allow us to see non-luminous objects such as our hands, the floor, and the people around us are lit by light rays that travel from a light source to the object and then bounce off the object towards our eyes.
