The phenomenon is called iridescence. It happens because in a thin film (like a soap bubble, or gasoline on water) there can be constructive interference in light waves as they bounce between the two surfaces of the film. The exact color depends very sensitively on the thickness of the film, which is why the colors seem to swirl around as minor variations in the thickness move through the substance.

Explain the principles behind the reason why you see colors on soap bubbles?
This works through interference patterns. The wall of the soap bubble is very thin - on the order of the wavelength of the light. This makes the interference patterns noticeable. The interference is caused between the light that is reflected from the front part of the bubble wall, and from the light reflected from the back part of the bubble wall.
Why does a soap bubble show beautiful colours when illuminated by white light?
A soap bubble shows beautiful colors when illuminated by white light due to interference of light waves. The thin film of soap in the bubble reflects light waves at different angles, causing some waves to interfere constructively and others to interfere destructively. This interference results in the different colors observed on the bubble's surface.
What Colour does blue surface absorbs?
A blue surface absorbs most colors of light but reflects blue light, which gives it its blue appearance. This means that the surface absorbs all colors of light except blue, which is reflected back to our eyes, making it appear blue.
Why do you see colors on soap bubbles?
It's called iridescence, which is an optical phenomenon which occurs when the hue of a multi-layered and semi-transparent object such as soap bubbles appears to change due to the phase shifting of light within the soap bubbles as the angle from which the bubbles is viewed changes.
How can you explain how objects appear to have color?
Objects appear to have color because of the way they interact with light. When light shines on an object, it absorbs some colors and reflects others. The colors that are reflected are what we see. This process is called selective absorption and reflection, and it is what gives objects their perceived color.
Why do colors appear on the surface of a soap bubble?
Colors appear on the surface of a soap bubble due to interference of light waves. When light hits the thin film of soap, some of it reflects off the outer surface and some reflects off the inner surface. These reflected waves interfere with each other, creating a pattern of colors based on the thickness of the film.
When a ray of white light hits an opaque surface with red orange yellow green and violet what colors will the surface appear?
The surface will appear white.

Why colour seen on soap bubble?
The color seen on a soap bubble is due to the phenomenon of thin-film interference. When light reflects off the two surfaces of the bubble film, some colors interfere constructively while others interfere destructively, causing certain colors to be more visible. This creates colorful patterns on the surface of the bubble.

Is there any difference between the colours emerging from a prism and the colours of a soap film seen in sunlight?
No. In soap bubbles the color you see is proportional to the thickness of the soap bubble, and not the angle. This is because in a soap bubble, the light you see is the sum of the light reflecting off of the outer surface and the inner surface, which cancel out and add to get various colors, whereas in a prism, light is simply reflected and dispersed at an angle based on its energy. The way they reflect on the inner surface and outer surface is different at different thicknesses of bubble. Waves that travel from air to water have their peaks become troughs and vice versa. Really thin bubbles do not reflect at all and appear black against a black background. This is because the wave bouncing off of the back side of the bubble cancels out with the one bouncing off of the front. Different thicknesses cancel out some frequencies while leaving others (for example a 200 micrometer bubble cancels out blue and leaves orange because the wavelength of blue light is just right to be canceled). Another interesting thing is that, since waves are periodic (repeat up and down) , a bubble with twice the thickness will cancel out the wave in the same way. So if you graph bubble thickness vs. color of bubble, you will get roygbiv roygbiv ... over and over.

Why do stars appear yellow?
Stars appear yellow because of their surface temperature. When a star is at a medium temperature, it emits a mix of colors that our eyes perceive as yellow. Stars cooler than the Sun appear more red, while hotter stars appear more blue.
What Colours absorb the red surface?
Blue and green are colors that absorb red light. This means that objects with a blue or green surface will appear to absorb red light and reflect the remaining visible wavelengths.
How to make a rainbow in a bubble?
you cant make a rainbow in a bubble. but you can see one if the bubble is in front or near the sun. you must look at it a certain way in order to see colors!
