Question

what are the different between deflection and reflection

Answer 1

Reflection always takes place following laws of reflection.

Deflation is non-directional movement.

Answer 2

Light is deflected; means it bounces back on the plane surface when it is bent by a gravitational force. For example, a mirror never reflects the exact sum of light; and it will bounce back on the other side. ... The deflections of waves like light consist of reflection and refraction.
