Investigating Refraction and Reflection
Light behaves in fascinating ways as it interacts with various materials. When light passes from one medium to another, such as from air to water, it shifts its path, a phenomenon known as refraction. This bending occurs because the speed of light changes in different mediums. The angle at which light bends depends on the degree of incidence and the refractive index of the materials involved. Reflection, on the other hand, occurs when light bounces off a surface. The law of reflection states that the degree of incidence equals the degree of reflection. Grasping these concepts allows us to explain a wide range of optical phenomena, from rainbows to mirrors.
