Question

Apparatus – Soap water, a small loop of wire.

If you dip the wire loop in the soap water and then blow on it, soap bubbles are formed. The beautiful colours of the rainbow are seen in these bubbles.

Answer 1

When the wire loop is dipped in soap water and air is blown through it, soap bubbles are formed. Different rainbow colours can be seen on the surface of these bubbles. These colours are produced because light falling on the thin soap film gets separated into different colours.
