Question

a ray of light makes an angle of 50° with the surface S1 of the glass slab . It's angle of incidence will be....a)50°b)40°c)140°d)0°

Answer 1

Given : a ray of light makes an angle of 50° with the surface S1 of the glass slab .

In simple words it is given that angle of reflection is = 50° .

Now ,

To Find :

Angle of Incidence.

Solution :

As we know angle of reflection = Angle of incidence

50° = 50°

Option A = 50° is correct .

Answer 2

Answer:

a)50

Explanation:

Hey there,

Since according to the law, angle of incidence is equal to angel of reflection. therefore A ray of light makes an angle of 50° with the surface S, of

the glass slab. Its angle of incidence will be 50 degree as per the rule.

Angle of incidence is the angle through which a ray of light falls on an object whereas angle of reflect is the angle through which that ray of light reflects from the surface of that same object.

I hope the answer was helpful.

Thanks.
