describe an experiment to verify the laws of reflection of light
Answers
Answer:
it can be understood by the following experiment.
Explanation:
take a polished regular mirror.
take a torch and on it.
place it in front of the mirror.
you experiences that the angle of reflection and angle of incidence would equal in the =and opposite directions.
to investigate:- laws of reflection
1. first law is angle of incidence is equal to the angle of reflection
2. the ray of incidence, normal and ray of reflection lies on the same plane.
Things required :- one plane mirror and a torch or lazer beam torch will be better
EXPERIMENT OF FIRST LAW
Procedure
put the plane mirror on a flat surface
take the lazer beam torch
and point it towards the mirror
switch it on
now you see in the opposite direction of the mirror
you can see the the reflected image of the beam on the opposite wall of the mirror
as you will change the angle of reflection I.e as you will change the angle of the torch you will observe that the reflected image will also change its position
this proves that tha angle of incidence is equal to the angle of reflection
EXPERIMENT OF SECOND LAW
as per the first experiment we get to know that the angle of reflection is equal to the angle of reflection
so it's clear that both angles lies on the same plane
Since the angles lie ons the same plane
therefore the rays also lies on the same plane.
hope it helps
