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 if
it 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 that
the 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.

When angle of incidence is zero?
When the angle of incidence is zero, the incident ray is perpendicular to the surface. This means the light ray travels straight along the normal and does not refract or bend. This phenomena is known as normal incidence.
What is angle of incidence of light?
The angle of incidence of light is the angle between the incoming light ray and the normal (a line perpendicular to the surface) of the medium the light is traveling through. It is measured from the normal to the incident ray.
What is the normal in refraction?
The normal in refraction is an imaginary line perpendicular to the surface where the light ray enters. It helps determine the angle of incidence and angle of refraction, and is used in Snell's Law to calculate how the light ray will bend when passing through different mediums.
A ray of light traveling from air to water will bend which direction?
The ray will bend towards the normal.
What is the angle of incidence for this ray of light?
The angle of incidence is the angle between the incident ray and the normal (perpendicular line) to the surface the ray is striking.
How are incident ray reflected ray and normal related?
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
Which angle is the angle of incidence?
The angle of incidence of a ray (or light or other electromagnetic radiation) to a surface is the angle between the incoming ray and the normal - which is perpendicular to the surface at the point of incidence
The angle of incidence is the angle between what and the normal of the surface?
The angle of incidence it he angle at which the incident ray stikes the plane of the surface.
What are angle of reflection and angle of incidence?
The angle of incidence is the angle between the incident ray of radiation (usually light) and the normal (perpendicular) at the point of incidence. Similarly, the angle of reflection is the angle between the reflected ray and the normal.
What is the ray of incidence?
The ray of incidence is the light ray hitting the mirror plane and the ray bouncing off is the reflection ray. An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence
What is a normal ray in a diagram of reflection of light?
A normal ray in a diagram of reflection of light represents the perpendicular line drawn at the point of incidence on a mirror or reflecting surface. It is used to show the angle of incidence and angle of reflection in relation to the mirror's surface.
What is the angle of incidence when a ray of light falls on spherical mirror from its centre of curvature?
That ray of light is just a radius of the sphere. It's perpendicular to the sphere everywhere, so the angle of incidence is zero ... the ray of light arrives along the normal to the mirror at any point.
