Question

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

Answer:

When light shines onto a bubble it appears to change colour. Unlike those seen in a rainbow, which arise from differential refraction, the colours seen in a soap bubble arise from interference of light reflecting off the front and back surfaces of the thin soap film.

Explanation:

Answer 2

Yes, the colors of the rainbow are seen in the bubbles.

Reason

• The soap bubbles that are formed on the wire loop are transparent and three-dimensional. Hence, they can act like a prism for the white light passing through them and divert the colors.

• A prism is a three-dimensional triangle that splits the white light into its seven basic colors when the white light is passed through it. The seven colors are arranged in the form of VIBGYOR according to their wavelengths- violet, indigo, blue, green, yellow, orange, and red.

• Similarly, the white light passing through the bubble is broken down into its seven constituent colors, and we can see the colors of the rainbow.
