The angle of reflection is: (a) 300 (b) 600 (c) 450 (d) none. 2. An object 20cm high is placed at a distance of 100 cm from a plane mirror .The size of the image will be. WebApr 8, 2024 · Refraction is the bending of light as it passes through a transparent substance. Water, sound, and other waves do it too. This bending had allowed the creation of magnifying glasses, prisms, lenses, etc. Here, the degree to which refraction occurs relies on the light's wavelength.

Peepholes in the doors, magnifying glasses, binoculars, cameras, lenses in the projectors, etc. use the principle of refraction of light. WebMar 22, 2015 · Laws of Refraction: 1. Incidence ray and refracted ray are on opposite sides of normal and are in different mediums. 2. Whenever light ray enters from rarer to denser medium, it slightly bents towards the normal and when it enters from denser to rarer medium it bents away from the normal. 3.
