Light

A mirror is a reflective surface. A lens, on the other hand, does not reflect light; it refracts it

This lesson will look at a multiple choice question on light and will ask you to find what angle from the center of the screen. This lesson will give a step by step in-depth explanation of the concept by looking at graphs and diagrams to derive formulas to solve.

This lesson will go through a problem and what occurs when light travels from air to acrylic and what happens to the angle, as well as what happens when the light goes from acrylic to air and what happens to the angle. An example will be shown how to find the angles.

This lesson is on diverging lens Ray Diagram. You will learn how to draw a ray diagram for a diverging lens. A diverging lens will be explained and its relation to a convex mirror. A step by step process of how to draw rays and its relation to principal axis, the extension and how it relates to the focus will be shown and explained.

This lesson will look at diagrams of converging and diverging lenses to explain their effect on a object's reflection from light rays. An explanation of how to draw the reflected rays will be explained in a step by step process to gain a better understanding of the concept.

This lesson will look at the belief that energy flows continuously. This lesson will look at an experiment to define and explain Blackbody radiation and Plancks quantum hypothesis. This lesson will give a step by step in-depth explanation of the concept by looking at graphs and diagrams to derive formulas to solve.

Snell's law is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water and glass.

A ground or molded piece of glass, plastic, or other transparent material with opposite surfaces either or both of which are curved, by means of which light rays are refracted so that they converge or diverge to form an image.

This lesson will explain the reflection of light and how it relates to the law of reflection of waves. The angle of incidence is equal to angle of reflection. The lesson will discuss the image produced by a mirror and how and why it has the same size as the object. Refraction will be explained as well. The lesson will discuss the index of refraction and a review of what the speed of light formulas are. These will be explained and their relation to waves.
