According to law of reflectionThe angle of incidence - the angle of reflection -x3B8- say-So- the angle between the incident and the reflected ray-x3B8-x3B8-2-x3B8-As per given condition- 2-x3B8-900or- -x3B8-450The angle of reflection is 450

According to law of reflectionThe angle of incidence = the angle of reflection =θ, say.So, the angle between the incident and the reflected ray=θ+θ=2θAs per given condition, 2θ=900or, θ=450The angle of reflection is 450

According to law of reflection
The angle of incidence $=$ the angle of reflection $= θ$ , say.
So, the angle between the incident and the reflected ray $= θ + θ = 2 θ$
As per given condition, $2 θ = 90^{0}$
or, $θ = 45^{0}$
The angle of reflection is $45^{0}$
