Reflection is the bouncing back of light when it hits a smooth surface, while refraction is the bending of light when it passes through a different medium.
The angle of incidence is equal to the angle of reflection. This is known as the law of reflection.
Total internal reflection occurs when a light ray strikes the boundary of two mediums at an angle greater than the critical angle, causing all of the light to be reflected back into the original medium.
The shape of a lens, specifically its curvature, determines the amount of bending that occurs when light passes through it. A convex lens will converge light, while a concave lens will diverge light.
A real image is formed when light rays actually converge at a point, while a virtual image is formed when light rays only appear to originate from a certain point but do not actually converge.
