State laws of refraction |
Answer» <p>Laws of Refraction</p><p>The angle of incidence is the angle between the incident ray and the normal; denoted as ‘i’. The angle of refraction is the angle between therefracted ray and the normal; denoted as ‘r’. Laws of refraction state that:</p><p>The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane.</p><p>The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.</p> | |
