Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

out the potency of the extract of the leaves from the plant camellis sinensis as an ink. Nowadays‚ ink is a pigment in a liquid or paste form used as colorants and dyes. Also‚ they are becoming more and more expensive because of their increasing purposes. Our research aims to produce this ink as a cheaper alternative to these commercial ones. Compared to the ink we are aiming to create‚ commercially produced inks are toxic and can be hazardous to a person’s health once there s a inapprpriate contact
