Question

during an experiment to verify the laws of reflection of sound a student draws the figure.AOB=76 FIND ANGLE of incidence

Answer 1

From the laws of reflection,

Angle of Incidence = Angle of Reflection...

So, angle AOC = angle BOC

i.e. i = r

Also, angle AOB is 76° = i + r

So, 2i = 76°

Hence, i = 38°
