Left becomes right and right becomes left.Ī kaleidoscope is a toy used to make lots of reflections of something. Calculate the angle of refraction for light as it passes from air to each of the mediums at. The image formed in the mirror is the same size as the object and forms at the same distance as the object is from the mirror. The angle of incidence is always equal to the angle of reflection. The angle of reflection is the angle formed by the normal and the light ray that is reflected ( the reflected ray). The angle of incidence is the one formed by the normal and the ray of light that hits the surface ( the incident ray). The red line is called the normal, which we draw vertically (at right angles) to the surface of the mirror to help us calculate the angles of incidence and reflection. (a) What is the index of refraction of a substance that has a critical angle of 68.4° when submerged in water What is the substance, based on Table 25. You can determine the index of refraction of a substance by determining its critical angle. Have a look at this diagram showing how light is reflected by a plane (flat) mirror: At what minimum angle will you get total internal reflection of light traveling in water and reflected from ice (OpenStax 7. Mirrors are very smooth surfaces and reflect light in a perfectly even manner. Smooth surfaces reflect light relatively evenly, whereas most other surfaces scatter it in all directions. How light is reflected depends on the surface. When light bounces off a surface, in science, we say it is reflected. We see things when light bounces off them and enters our eyes.
