WebSince a convex lens has two principal foci, so it has two focal lengths, known as first focal length (f1) and the second focal length (f2). (i) First Focal length : The distance of the first principal focus of the lens from the optical centre ‘O’ of the lens is called first focal length of convex lens. It is represented by ‘f1’. i.e ... WebNov 9, 2024 · The distance of the position of the image of an object on the principal axis from the pole of a spherical mirror is known as the image distance. It is denoted by v.

the distance between pole and the principal focus of the mirror is

WebThe distance between the pole and the principal focus of a spherical mirror is called the focal length of the mirror. In figure (1) and (2), PF is the focal length. In a spherical mirror, the focal length is half of the radius of curvature. Therefore, f = r/2. The principal focus of Concave Mirror: WebIt is denoted by the letter ‘c’. b. Radius of Curvature (r): It’s the linear distance between Pole and the Center of curvature. c. Pole (p) : It’s the midpoint of the spherical mirror. d. Principal axis: It’s an imaginary line passing through the optical centre and the centre of curvature of any lens or a spherical mirror. e. Aperture: WebApr 9, 2024 · When the distance between the objects in the mirror is increased, the size of the image gets diminished and a real image is formed. The real image of a concave mirror … brandywyne east brielle nj
