Photoelectric effect, Compton Effect will be explained by using on the basis of the theory as proposed by Einstein . Its speed measure by Romer (1678 AD). . 🎻 Refractive index: it is a medium which is defined using the ratio of light in vacuum to the speed of light in medium. Refractive Index varies in various medium. In small refractive index velocity of light is large.Sun light takes 8 minutes to reach to earth. . 🎻 Reflection of Light: One way to change the direction of light is to let it fall on a shiny surface.For example, a shining stainless steel plate or a shining steel spoon can change the direction of light.The distance between mirror to object and mirror to image is equal distance.Water surface is a medium of change light and its act like a mirror.When light falls in mirror its chan...
