Explanation Introduction: The law of refraction also known as the Snell's law is used to govern the change of direction of light as it propagates from one medium to another. The law also states that the incident ray, the reflected ray and the normal, all lies in the same plane. The thermometers which are used to measure the temperature have a front side as a curved surface. The reason behind this is to magnify the scale of the thermometer so that they are visible without any parallax error...
