Explain the principles behind the reason why you see colours on soap bubbles Detailed explanation of the related scientific theory and required conditions must be provided?

Answer 1

This sounds like a homework problem, so I will point you in a direction and let you do the rest of the work.

The effect is due to wave canceling/enhancing interference between light reflecting from near and far sides a thin film of transparent material. Different colors appear in places where the thickness of the film differs.

This is also the same effect as the colors seen looking at a thin oil slick on water. Except the thin film here is oil, not soap bubble solution.

Answer 2

Soap bubbles exhibit colors due to thin film interference, a phenomenon that occurs when light waves reflect and interfere with each other as they pass through the thin layer of soap film. This interference leads to certain wavelengths of light being enhanced and others being canceled out, resulting in the vibrant colors we see on the soap bubble. The thickness of the soap film determines the colors observed, as different thicknesses lead to different interference patterns. The conditions required for this phenomenon to occur include a thin layer of soap film, light hitting the film at a small angle, and the light being composed of multiple wavelengths.
