With the help of an activity verify the law of reflection |
|
Answer» tion:: Verification of laws of REFLECTION Required material: MIRROR strip, drawing board, white paper, pins, clamps, scale and pencil Procedure: Take a drawing board and FIX a white paper on it with the help of clamps.Draw a straight LINE AB at the centre of the paper and also a normal (ON) to AB at the point ‘O’.Draw a straight line PQ MAKING certain angle (angle i) with ON as shown in figure.Fix two pins at the points P and Q on the paper vertically. Observe the image P| of the pin P and Q| of the pin Q, in the mirror kept along the line AB. Fix two more pins R and S such that they are in the same line as that of P| and Q|Join R, S and O as shown in figure.Measure the angle between RS and ON (angle of reflection). You can conclude that that angle of incidence = angle of reflection |
