While doing an experiment for the determination of focal length of a convex lens, Raja Suddenly dropped the lens. It got broken into two halves along the axis. If the continues his experiment with the same lens,
(a) can he get the image?
(b) is there any change in the focal length?

Text Solution

Verified by Experts

(a) Yes he can get the image , because the lens broken into halves along the axis.
(b) No , focal length remains the same for the lens if its broken (or) not broken.

    A convex lens is held in water. What would be the change in the focal length?

    A concave lens is placed in water. Will there be any change in focal length? Give reason.

    A convex lens is placed in water. a. Will there be any change in its focal length? B. Give reason.

    Briefly explain, how the focal length of a convex lens changes with increases in wavelength of incident light.

    Arrange in sequence , the steps to find the focal length of a convex lens. Measure the distance between lens and screen, find the focal length 'f', focus the lens on a distant object, Adjust the screen to catch a clear image.

    The teacher shows a thin lens and a thick lens. a. Which of these lens forms more enlarged image ? b. Which lens has greater focal length?

    If the distance D between an object and screen is greater than 4 times the focal length of a convex lens, then there are two positions of the lens for which images are formed on the screen. This method is called conjugate foci method. If d is the distance between the two positions of the lens, obtain the equation for focal length of the convex lens.
