9. State laws of reflection of light with suitable digram ​

Answer»

I = Incident rayR = Reflected rayN = Normal  ∠ i = angle of incidence  ∠ r = angle of reflectionThere are two BASIC laws of reflection of LIGHT -(i) The incident ray the reflected ray and the normal to the REFLECTING    the SURFACE at the point of incidence lie in the same plane ;(ii) The angle of incidence is always equal to the angle of reflection i.e      ∠ i = ∠r
