Question

Which of the following lenses would you prefer to use while reading small letters found in a dictionary? a) A convex lens of focal length 50 cm. Aconcave lens of focal length 50 cm. ( A convex lens of focal length 5 cm. A concave lens of focal length 5 cm. We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case. Name the type of mirror used in the following situations. Headlights of a car, encare (b) Side/rear-view mirror of a vehicle, convex a Solar furnace. Cenave Support your answer with reason. One-half of a convex lens is covered with a black paper. Will this lens produce complete image of the object? Verify your answer experimentally. Explain you observations An object 5 cm in length is held 25 cm away from a converging lens of focal lengt 10 сın. Draw the ray diagram and find the position, size and the nature of the mirrot​

Answer 1

Answer:

Explanation:

c  A convex lens forms an enlarged and virtual image of an object when the object is placed at the focal point and between the pole and focus. Convex lenses are also known as converging lenses since the rays converge after falling on the convex lens
