5. A prism works by refracting or bending incoming white light. When white light enters a prism, it slows down and changes direction due to the different refractive indices of the prism's material. This causes the different colors of light to separate and bend at different angles. The process is known as dispersion. As a result, when the separated colors of light exit the prism, they spread out and form a spectrum of colors, creating the appearance of a rainbow.
6. Reflection of light occurs when light rays bounce off a surface. The key factors that determine the angle at which light is reflected from a surface are the angle of incidence and the angle of reflection. The angle of incidence is the angle at which the incoming light ray strikes the surface, while the angle of reflection is the angle at which the reflected light ray bounces off the surface. According to the law of reflection, the angle of incidence is equal to the angle of reflection. Additionally, the smoothness and nature of the surface play a role in determining the angle of reflection. A smooth, polished surface will reflect light in a regular and predictable manner, whereas a rough or uneven surface will scatter the light, causing diffuse reflection.
