Question: Explain the term photoelectric emission?
The refractive index of a material is a measure of how much it can bend or refract light as it passes through it. A refractive index of 1.65 means that the material can bend light 1.65 times as much as air or vacuum. The higher the refractive index of a material, the slower the speed of light through it. This property is important in optics and can be used to create lenses, prisms, and other optical devices.
