### Why ray does not refract when it passes through optical centre?

It does. But when the ray arrives perpendicular to the boundary, the angle of incidence and the angle of refraction are both zero, so its direction doesn't change.

### 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.

### What will be the reason - a plane mirror has an angle of incidence O degree?

The light ray arrives perpendicular to the plane of the mirror.

### What is an angle at which a beam of light arrives at a surface?

It is the angle of incidence.

### What is the angle between the angle of incidence and the angle of reflection?

the angle of incidence is the initial ray angle and the angle of reflection is the reflected ray angle

### 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

### How are incident ray reflected ray 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

### The angle of incidence is the angle between the incident ray and the?

The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.

### A light ray hitting a mirror at an angle is reflected off at angle?

The angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.
