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.

The focal point of a concave mirror is 5 cm what is its center of curvature?
10 cm from the mirror.
What is the largest possible angle of incidence for a light ray traveling toward a mirror?
90 degrees is the largest possible angle of incidence because it is then parallel to the face of the mirror and is grazing the mirror.
Is the focal length equal to the radius of curvature of the mirror?
yes
What is the relation between focal length and center of curvature?
The focal length of a concave mirror is about equal to half of its radius of curvature.
How can find the radius of curvature?
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.
What is definition for the centre of curvature of a spherical mirror?
It is the center of the imaginary sphere to which the mirror belongs.
What is the center of spherical mirror?
The geometric centre of a spherical mirror is called its pole. The centre of the hollow sphere for which the mirror is a part, is called the centre of curvature. The line joining the centre of curvature and the pole is the principal axis. A light ray incident on a spherical mirror, after reflection appears to pass through the principal focus in the case of a convex mirror and passes through the focus in the case of concave mirror. The diameter of the spherical mirror gives the measure of its aperture
What is the ratio of focal length of a spherical mirror to its radius curvature?
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
What are spherical mirrors?
The most curved mirrors are spherical mirrors. The centre of curved surface is called center of curvature. There are two kinds of spherical mirrors. Concave and convex mirror.
What is the center of curvature of the mirror?
the centre of sphere is known as centre of curvature
How can a spherical mirror become a plane mirror?
By increasing its radius of curvature to infinity.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
Which doesnot change when spherical mirror is broken?
Its radius of curvature and its reflecting property
Where will the image form when you place an object on the principal axis of a concave mirror at a point between focus and centre of curvature?
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
A line joining pole and centre of curvature of the mirror is called?
PRINCIPAL AXIS
How does a concave mirror work?
A concave mirror is a spherical mirror which is curved inward, where the inside surface is reflective. They work by reflecting the light captured into the centre of the mirror, creating a focal point in the centre of the mirror.
Examples of concave and convex mirrors?
Convex means rounded or curved like the exterior of a circle or sphere. Also called as fish eye or diverging mirror. The mirror coating of the concave mirror is on the outside of the spherical surface. In concave mirrors, the center of curvature and the reflecting surface fall on the same side of the mirror.
