20/1/12 Friday Physics Grade---8



An experiment was done to prove that image formed by convex lens are always inverted & real.

Students used burning candle, stand, convex lens, concave lens & screen. when convex lens was placed in front of screen they were able to capture the image & when it was replaced by concave the image was not formed on screen. So, it was clear that images formed by concave lens are always virtual.

Fun with doing helped students to understand the concept of lens in a better manner.
