What is a lens Class 10?
A lens is a piece of transparent glass which concentrates or disperses light rays when passes through them by refraction.
What is the lens formula Class 10?
Solution : The lens formula is `1/v-1/u=1/f` where u – object distance, v – image distance and f is focal length.
WHAT IS lens class 7th?
WHAT IS lens answer?
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.
What is mirror formula and lens formula?
A mirror can be plane or spherical (concave or convex) A lens is usually curved from either one or both surfaces. Mirror formula is 1/f = 1/v + 1/u. Lena formula is 1/f = 1/v – 1/u.

What is the formula for lens?
Lens equation or lens formula is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, Lens Formula – 1/u + 1/v = 1/f. where. v = Distance of the image from the lens. u = Distance of the object from the lens. f = Focal length of the lens.
What is the lens equation for convex lens?
The Lens Equation. An image formed by a convex lens is described by the lens equation 1 u + 1 v = 1 f where uis the distance of the object from the lens; vis the distance of the image from the lens and fis the focal length, i.e., the distance of the focus from the lens.
What is the formula for the focal length of a lens?
Focal length of lenses 2 The focal length of a thin lens depends on the radius of curvature, R,of each surface of the lens, and the index of refraction, n, of the lens material. The lens maker’s equation for the focal length, f, of a lens is1 1 f =(n− 1) 1 R1 + 1 R2 . (1) Because the surface of a lens may be either convex or concave, there are sign
How to calculate magnification of a lens?
Calculating magnification with the help of lens formula: Magnification of a lens is defined as the ratio of the height of an image to the height of an object. It is also given in terms of image distance and object distance. It is equal to the ratio of image distance to that of object distance.
