lens and the screen

C

object and the screen

D

lens and the screen and also object and the screen

Text Solution

A student obtains a blurred image of a distant object on a screen using a convex lens. To obtain a distinct image on the screen he should move the lens

While determining the focal length of a concave mirror, a student obtained the image of a distant object on a screen. In order to get the focal length of the mirror, the student should measure the distance :

if you focus the image of a distant object, whose shape is given below, on a screen using a convex lens, the shape of the image of this object on the screen would be :

Find the distance of an object from a convex lens if image is two times magnified. Focal length of the lens is 10cm

It was observed that when the distance between an object and a lens decreases, the size of the image increases. What is the nature of this lens? If you keep on decreasing the distance between the object and the lens, will you still able to obtain the image on the screen? Explain

The steps followed in determining the focal length of a given convex lens by obtaining a sharp image of a distant object are listed below but they are not in correct order. (A) Measure the distance between the lens and screen. (B) Adjust the position of the lens to form a sharp image. (C) Select a suitable distant object. (D) Hold the lens between the object and the screen with its faces parallel to the screen What should be the correct sequence of steps?

Try this Material: Convex lens, screen, metre scale, stand for the lens etc. Method: Keeping the screen fixed, obtain a clear image of a distant object like a tree or a building with the help of the lens on the screen. Measure the distance between the screen and the lens with the help of the metre scale. Now tum the other side of the lens towards the screen. Again obtain a clear image of the distant object on the screen by moving the lens forward or backward. Measure the distance between the screen and the lens again. What will happen if you use a concave lens in this experiment?
