Answer:
Angle of reflection will be [tex]40^{\circ}[/tex]
Explanation:
We have given angle of incidence from the smooth surface is [tex]40^{\circ}[/tex]
So angle of incidence = [tex]40^{\circ}[/tex]
We have to find the angle of reflection
From l;aw of reflection we know that angle of reflection is equal to the angle of incidence
So angle of reflection will be equal to [tex]40^{\circ}[/tex]
