Question

Im
b) List out the material required and write the experimental
procedure to find the image distance using convex lens when
an object is kept infront of it on its principal axis at different
locations.​

Answer 1

Materials : convex lens, any object

Explanation:

place the object in front of the mirror the image formed is looking that the object is closed to the mirror if kept far from it

Answer 2

convex lens, Measuring scale, Optical bench, needle, candle

Explanation:

material needed:

• convex lens
• Optical bench for the experiment
• piece of white paper for getting image
• V - stand for placing convex lens
• candle for getting image
• measuring scale for measuring focal length

hence, To find the image distance using a convex lens when an object is kept in front of it on its principal axis we need convex lens, Measuring scale, Optical bench, needle, candle
