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 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 definition for the centre of curvature of a spherical mirror?
The center of curvature of a spherical mirror is the point at the center of the sphere from which the mirror is a part. It is located at a distance equal to the radius of the sphere. The center of curvature is an important point for determining the focal length and the magnification of the mirror.
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.
How will a ray directed towards the centre of curvature of a convex mirror be reflected?
A ray directed towards the centre of curvature of a convex mirror will reflect back on itself along the same path. This is because the centre of curvature is located on the normal line, so the angle of incidence and the angle of reflection will be equal due to the principle of reflection.
How can a spherical mirror become a plane mirror?
By increasing its radius of curvature to infinity.
Which doesnot change when spherical mirror is broken?
Its radius of curvature and its reflecting property
The relation between focal length and radius of curvature of spherical mirror is?
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
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?
The image will form behind the mirror, between the focus and the center of curvature, and it will be a virtual, upright, and magnified image.
What is the center of curvature of the mirror?
The center of curvature of a mirror is the point located at a distance equal to the radius of curvature from the mirror's vertex. It is the center of the sphere of which the mirror forms a part. Light rays that are reflected from the mirror and pass through this point are either parallel to the principal axis (for concave mirrors) or appear to diverge from this point (for convex mirrors).
A line joining pole and centre of curvature of the mirror is called?
The line joining the pole and the centre of curvature of a mirror is called the principal axis. This line is a key reference point for determining the focal length and characteristics of the mirror.
Is plane mirror a spherical mirror why?
No, a plane mirror is not a spherical mirror. A plane mirror has a flat reflective surface, while a spherical mirror has a curved reflective surface. The shape of the mirror affects the way light is reflected, with spherical mirrors causing light rays to converge or diverge depending on their curvature.
