GCSE Refraction of light is a fascinating phenomenon that occurs when light travels from one transparent medium to another. In this lesson, you will learn about the concept of refraction and its underlying principles. You will explore how light changes its direction and speed as it passes from one medium to another, causing it to bend or refract. You will discover the laws of refraction, which explain the relationship between the angles of incidence and refraction, and how they are affected by the refractive indices of the media involved. Additionally, you will explore practical applications of refraction, such as lenses and prisms, and how they are used in everyday life, from eyeglasses to telescopes.
