CHAPTER10 Light – Reflection and Refraction
ncert.nic.inWe shall try to understand in this Chapter the r eflection of light by spherical mirrors and refraction of light and their application in real life situations. 10.1 REFLECTION OF LIGHT A highly polished surface, such as a mirror, reflects most of the light falling on it. Y ou ar e already familiar with the laws of r eflection of light.

faisalj.webs.comTotal Internal Reflection: Consider a ray of light passing from glass to air. If the ray is along the normal then it will not refract. When the angle of incidence is small; we get a weak internally reflected ray (light grey) and strong refracted ray (dark grey). As we increase the angle of incidence, the angle of refraction also increases.

www.utsa.edureflection. Refraction The most common example of refraction is the bending of light on passing from air to a liquid, which causes submerged objects to appear displaced from their actual positions. Refraction is also the reason that prisms separate white light into its constituent colors. Refraction is commonly explained in terms
