PPT-Refraction Phenomena

Apparent Depth amp Volume Refraction can change the perception of depth and volume because the apparent path of light does not equal the actual path of light Underwater Vision Atmospheric Effects. RAY OPTICS -I Refraction of Light: Refraction is the phenomenon of change in the path of light as it travels from one medium to another (when the ray of light is incident obliquely). It can also be de How light can trick us. Naturally Occurring Phenomena. Apparent depth. Flattened sun and sunsets. Mirages. Shimmering. Rainbows. Apparent depth. The depth that an object appears to be due to the refraction of light in a transparent medium. When light travels from one material to another it usually changes direction. The bending of light that occurs at the borderline of two materials is called . refraction. Geometrical concepts:. -incident ray. Mr. . . Dvorsky. SNC2D1. Review of last chapter. From the last chapter, we know how light behaves when it travels in space or in the air – i.e. it travels in a straight line.. When light strikes a plane mirror, the angle of incidence = the angle of reflection. . What has happened in each example and why?. I think this is called.... It happens when.... It happens because.... The air is.... The water is.... The light usually. travels...but when it hits water.... What is Refraction?. In a vacuum (air) light travels in straight lines.. But what happens when light travels from one material into another?. Like for example, from air to water?. What Happens When Light hits a Medium. Presented by: Vandana Bathla & Eric Williams. Light Refraction. Have you ever wondered why it appears we see puddles of water on a highway on a hot summer day?. What you are seeing is not really water, but a mirage.. Refraction occurs at a boundary. The speed of light must change at the boundary. The angle of the light ray is measured from the normal, as was the case with reflection. If the speed slows across the boundary, the refracted angle will be smaller – the light ray will bend toward the normal.. . . 4. . S. unset. . . Serbian team. Regional Center For Talented Youth.

The visible Sun disk touches the horizon and after a particular time interval disappears behind the horizon. What is the duration of this time interval? Explain the optical phenomena observed during a sunset.. Atmospheric Sciences 101, W19. The effects of the atmosphere and hydrometeors (e.g., rain) on visible light. Visible light is made up of a spectrum of colors from red (long wavelengths) to violet (short wavelengths). What is refraction?. What causes refraction?. What are some examples of refraction of light that show why it is important?. Refraction of Light - Defined. Refraction of light occurs when a light wave moves from a vacuum (or a medium) into another medium (or a vacuum). When a wave changes media, its ____________ changes..
