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 Unit 8. How we use light to see.. To the physicist, the colors of things are not in the substances of the things themselves.. Color is in the eye of the beholder and is provoked by the frequencies of light emitted or reflected by things.. 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. pp. 562 -567. Mr. Richter. Agenda. Warm-Up. Introduction to Refraction Demo. Reminder: Quarter 3 Ends Friday. Notes:. Refraction. Index of Refraction. Why Light Bends. Refracted Images. Snell’s Law. 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.

When a wave reaches a boundary between two media, usually some or all of the wave bounces back into the first medium.. A metal surface is rigid to light waves that shine upon it. . Light .

Short Streamer=Missing Low-Wavenumber Components . light bends or refracts when it moves from one medium to another. the light bends because it changes speed. if light slows down it bends toward the normal. if light speeds up it bends away from the normal. Vocabulary . Refraction-. . the bending of light as it passes from one material into another.. Prism-. . a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms. 1. The problem. . 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.. o. . What is the angle of incidence in glass?. Problem 1. Light travels from crown glass (n=1.52) into air (n=1.00). The angle of refraction in air is 60. o. . What is the angle of incidence in glass?. Stephen Kyle. University College London. s.kyle@ucl.ac.uk. Co-authors: . Stuart Robson (UCL).
