(b) Find the distance of the image from the object. (c) What is the focal length of the mirror? (d) Draw the ray diagram to show the image formation in this case.

Answer 1

Answer:

You might be knowing that power of lens is reciprocal of focal length of the lens. So if you had a lens of large focal length than power is too low .

It's focus would be at large distance from you. So to see clearly you have to sit farther from it

Just imagine to see a small insect you holded your lens beyond 100 cms so you are sitting 200 cms from the insect.

This large focal length is available in your spectacles that you wear.They let us to see images far away from us.
