Reflection is the process in which light bounces off a surface such as a mirror or a window, while refraction is the bending of light through a transparent material such as water. That's the basic definition, but the rest of the theory and the practical lesson is up to you!
4 Reflection The law of reflection states that the angle of reflection is equal to the angle of incidence. A ray that hits the surface is the incident ray. The ray that bounces off the surface is the reflected ray. *An incidence is the intersection of a line, or something moving in a straight line, such as a beam of light, with a surface.

Reflection and Refraction. Chapter 29. Reflection and Refraction. Reflection. Reflection: when a wave reaches the boundary between two mediums, it bounces back into the first medium based on rigidity If second medium is very rigid – all energy is reflected. 465 views • 13 slides
Understand how light behaves when it hits objects - reflects, refracts, or gets absorbed. Discover the laws of reflection and examples with mirrors. Learn about concave and convex mirrors, refraction through prisms and diamonds, and light absorption effects. Dive into the science of rainbows and refraction in water. Find out how objects like prisms, water, and mirrors interact with light ...
Properties of light waves discussed include reflection, refraction, transmission, and absorption. Reflection is the bending of light at an interface between two media, governed by the law of reflection. Refraction is also the bending of light, but as it passes between media of different densities, which causes changes in light's speed and ...

In a convex mirror, rays of light parallel to the principal axis after . reflection get diverged and appear to come from a point on the . principal axis behind the mirror called principal focus (F). vi) Focal length:-is the distance between the pole and principal ...
Title: Light, Reflection, and Refraction 1 Light, Reflection, and Refraction. Chapters 14 and 15; 2 Electromagnetic Waves. An electromagnetic wave is composed of a magnetic field wave perpendicular to an electric field wave ; All objects that are not at absolute zero emit EMWs. The hotter the object the more waves they emit.

Diffuse reflection (irregular reflection), the irregular surface can be considered to be made up of a large number of small planar reflecting surfaces positioned at slightly different angles. 5 Refraction The bending or change in direction of light is known as Refraction.
Reflection, Diffraction, and Refraction, continued Reflection occurs when a wave meets a boundary. reflection: the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through Examples: The reflection of light waves in a lake can create a mirror image of a landscape. Water waves are reflected when they hit the side of a boat.
