When a light passes through a concave mirror, the light is reflected in a way that converges to a single point, known as the focal point. This type of reflection is called a converging reflection.
The focus and focal length of a spherical mirror are determined by its curvature. The focal length is equal to half the radius of curvature. The focus is located at the center of the mirror.
When the angle of incidence is equal to the angle of reflection in a spherical mirror, it is known as the “normal incidence” condition. This occurs when a light ray is incident on the mirror surface at a 90 degree angle.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence (the angle at which the light strikes the surface) is equal to the angle of reflection (the angle at which the light reflects off the surface). This law applies to all types of light and all …
what is pole, principle axis, Reflection in spherical mirror ? A pole in a spherical mirror is the point of the surface of the mirror that is farthest away from the center of curvature. It is the point at which the light rays that strike the mirror converge. Principle axis in a spherical mirror is …
The aperture of a mirror is the diameter of its reflecting surface. It is usually measured in millimeters (mm). A full-aperture mirror is one that has a diameter equal to its focal length. For example, a 100mm-focal-length mirror would have an aperture of 100mm.
The centre of curvature of a curved surface is the point from which the normal to the surface at any point on it appears to emanate. It is the centre of a circle or sphere whose surface intersects the surface at the same point, and this circle or sphere is the osculating sphere at the …
what is concave mirror and convex mirror ? A concave mirror is a curved mirror with a inwardly curved reflecting surface. Light rays that enter the mirror parallel to its principal axis are reflected to a focal point. This type of mirror is commonly used in optical devices such as telescopes, microscopes, and even makeup …

The peculiarities of a reflecting surface in a spherical mirror are: The reflecting surface of a spherical mirror is curved. All incident rays from a given point on the object are reflected in such a way that they appear to originate from a single point on the other side of the mirror, called the focus. …
A spherical mirror is a curved mirror that has the same radius of curvature in every direction. It is a type of concave mirror, meaning it is curved inward. The most common type of spherical mirror is the convex mirror, which has a bulging outward curved surface. This type of mirror is used to reflect …
