Yes.
The angle of incidence is 0 degrees for normal incidence, meaning the light ray hits the mirror perpendicularly. The angle of reflection is also 0 degrees, as the reflected ray will be in the same direction as the incident ray.
You don't say whether you're talking about reflection or refraction. But either way,a light ray that is incident normal to the surface follows the same simple rule as ifit had been incident at any other angle.-- For reflection, the rule is: Angle of reflection = angle of incidence.At normal incidence, the angle between the incident ray and the normal is zero,so the angle between the reflected ray and the normal is also zero. Notice thatthe ray certainly does bend ... its original direction is bent by 180 degrees.-- For refraction, the rule is (Snell's law): sin(Θ2) = n2/n1 sin(Θ1)At normal incidence, sin(Θ1) = 0 , so sin (Θ2) also works out to zero in the 2nd medium.
0(zero) Angle of incidence = angle of reflection
When a ray falls normally on a plane mirror, it is reflected back along the same path due to the law of reflection, which states that the angle of incidence is equal to the angle of reflection. Since the incident angle is zero degrees, the reflected ray also follows the same path.

Still zero.
Zero divided by anything is still zero.
When the angle of incidence is zero, it indicates that the incident ray is perpendicular to the surface. In this case, the angle of refraction needs to be zero as well in order to maintain the direction of the light without any deviation. This ensures that the light continues to travel in a straight line as it passes through the interface between the two mediums.
Of course still zero.
That happens when the incident ray is perpendicular to the surface at the point of incidence.
When an object is still it has no momentum. That is, the momentum is zero.
