Answer 1

4 What are the conditions nesse sary to form virtual inage using a converging lens. A virtual image is formed if the object is placed less than the focal length from lens. eging the conv Lets see this with say Liagram 2F F F 2 backward Its been that in this case the light rays diveage after refracting through the lens. cohen refraised ray cliverges a virtual image is formed. The image location can be found by tracing the light rays cintil they intersect. what type of lens is used in a magnifying glass, Explain how to use the magnifying glass properly. to see the largest possible énage. where should your eye be located and where should the object be located ?

virtual image say virtual the object The type of lens used used in a in a magnifying glass es diverging lens conven lang. As explained above. A converging lens. produces. magnified énage inage when the object is placed in front of the focal point. distance be less than that of the focal length of the lens. such a position the upright and magnified. And also to taken into consider that the the object distance should be not be very than the focal length a very low distance will create overly magnified image. eye should be located at the other side of the lens to the lens. For inage will be we need much less The lens near Image objects + 2F F F 2F
