[@sejalrajput26]

Light is a form of energy which enables us to see the objects . Reflection = when a light falls on a shiny surface it bounces back to other Direction Laws of reflection = there are 2 laws 1= Angle of incidence = Angle of reflection 2=incident ray , reflection ray and normal line lies on a same point If reflection surface is inside then it is concave mirror If reflecting surface is outside then it is convex mirror An image that is formed on screen is said to be real image An image that appears to formed behind the mirror is said to be virtual image Convex lens is thicker in middle and thinner at the edges Concave lens is thicker at the edges and thinner at middle Lateral inversion = when we look at our own image in plane mirror our right side appear to left and left side appear to be right side The phenomenon of breaking white light into a band of 7 colours VIBGYOR called dispersion 2:30 Rectilinear Propagation of light
