Answer 1

Answer:

Hope it's helpful for you.....

Answer 2

Answer:zero, zero

Explanation: incident normal to the plane means angle between incident angle and normal is zero from snell's law angle of incident is = to angle of reflection hence both incident and reflection is zero

Note angle is taken from normal

Normal is an imaganary line drawn perpendicular {90 degrees } to the plane mirror i.e plane and normal makes 90 degrees
