Question

When concave lens is held away from the object what type of image does it form

Answer 1

Answer:

When the object is placed very close to the lens, the image formed is virtual, erect and magnified. When used to see objects magnified, the convex lens is called a magnifying glass. A concave lens always forms erect, virtual and smaller image than the object. White light is composed of seven colours.

Get some lenses. Touch and feel them. Can you find some difference just by touching? Those lenses which feel thicker in the middle than at the edges are convex lenses. Those which feel thinner in the middle than at the edges are concave lenses. Notice that the lenses are transparent and light can pass through them.
