Question

If a wave hits a smooth surface at an angle of incidence of 40 degrees, the angle of reflection is

Answer 1

40 degrees

Step-by-step explanation:

got it right

Answer 2

Angle of reflection will be
`40^(\circ)`

Step-by-step explanation:

We have given angle of incidence from the smooth surface is
`40^(\circ)`

So angle of incidence =
`40^(\circ)`

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
`40^(\circ)`
