Question

observation table
angle of incidence,
angle of reflection​

Answer 1

Answer:

deflection is a thing that affects the shadow in which it is black colour reflection can be done when an opaque objects communities path

Answer 2

Answer:

$\: \: \:$

1. if angle of incidence is 30° then reflection will be 30° because we know that ∠r = ∠i

2. similarly , angle of reflection will be 45°

3. similarly , angle of incidence will be 60°
