In the figure shown, if angle i increases slightly, angler will angle of
reflection
angle of
incidence
a. remain the same
Oc. increase
Ob disappear
O d. decrease

Explanation:

According to law of reflection of light ,

angle of incidence = angle of reflection

angle of incidence = i

angle of reflection = r

when angle of incidence increases to i₁ and angle of reflection becomes r₁

According to law of reflection,

i₁ = r₁

i₁ - i = r₁ - r

increase in angle of incidence = increase in angle of reflection .

So angle of reflection also increases .
