![]() The bottom two thirds of the image is grey. Item contShown is a colour diagram of a shopping cart moving from pavement onto grass. Each of these angles are also labelled with the theta symbol and a lowercase, italicized i, and the theta symbol and a lowercase, italicized r. The right illustration is the same as the left, except that the angles of the arrows are further away from "Normal". The one leading to the "Reflected Light" arrow is labelled with a theta symbol and a lowercase, italicized r. The one leading to the "Incident Light" arrow is labelled with a theta symbol and a lower case, italicized i. This is labelled, "Reflected Light" in red letters. A red arrow points diagonally up and right from the top centre of the surface. This is labelled "Incident Light" in blue letters. In the left illustration, a blue arrow points diagonally, down and right, to top centre of the surface. These are labelled "Surface." Vertical, dashed lines stretch down the centre of each illustration, ending at the top centre of each rectangle. Shown are two colour illustrations of the angles of light reflecting off surfaces.īoth illustrations have a long, flat, grey rectangle along the bottom edge. Light reflecting off two surfaces (©2019 Let’s Talk Science). The symbol Ɵ means “angle'' and arrows represent rays of light. The angle of incidence is equal to the angle of reflection.The perpendicular line we call the normal. The angle between the reflected light and a line perpendicular to the surface we call the angle of reflection. The angle between the incoming light and a line perpendicular to the surface we call the angle of incidence. Light is reflected at the same angle that it hits the surface.Here are some things to remember about reflection. The reflected light continues to travel in a straight line, but in a different direction. Reflection occurs when light traveling through one material bounces off a different material. The water, and the sky above are both dark blue. All the buildings and their lights are reflected, upside down, in the calm water in the foreground. The CN Tower is to the left, lit up in red. ![]() High rise office buildings are close together along the horizon. Shown is a colour photograph of a city at night, and its reflection in water. ![]() Open Professional Learning × Close Professional Learning Open Educational Resources × Close Educational Resources
