Question

State the laws of reflection and describe an experiment to verify them.

ICSE Class 9 Physics Chapter Reflection of Light

Answer 1

the two laws of reflection are

angle of incidence is always equal to the angle of reflection.
2. incident ray normal and reflected ray always lie on a same plane

when you draw a diagram keeping in mind the laws of reflection you keep a mirror just on the mirror you have drawn and place 2pins on angle I and at the distance and length place another 2 pins them measure the angle

(i) The incident ray, the reflected ray and the normal at the point of incidence, lie in the same plane.

(ii) The angle of incidence and angle of reflection are equal i.e. ∠i = ∠r. Take a wooden drawing board and fix a white sheet of paper on it. ... Remove the pins and draw small circles around the pin pricks.
