In the experiment, when the object is kept at a distance between F and 2F, the image will be formed • The nature of the Image formed is Parallel rays of light are refracted by a convex lens to a point called the The location and nature of the image depends upon the distance of the • from the lens. Any lens forms an image by a phenomena : where the light rays bend because the : changes when it enters into called another medium.
Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
Using Lens formula and Magnification relation to solve the problem
Given data : Object distance u = -2F
Now, using Lens formula :
1/v - 1/u = 1/F
where, v = image distance ; F = focal length
i.e. 1/v - (-1/2F) = 1/F
i.e. 1/v = 1/F - 1/2F
i.e. 1/v = 1/2F
i.e. v = 2F -----------> image is formed on another side of the lens at a distance of 2F
