Water with a small coating of soap on either side creates bubbles. White light combines all of the colors of light. When light strikes on a bubble, it bounces around the layers, some of which reflect back to our sight. The colors you obtain are determined by the thickness of the water. If the water is thick enough for only certain wavelengths of light to pass through, then only those colors will be visible.
Bubbles are simply spheres of vapor that float in a liquid. A bubble's color depends on how much light is reflected into your eye when you look at it. If the bubble is thin enough so that all colours of light can get through it, then it will appear white to you. If it only lets red or blue light through, then it will appear colored that way too. But if you blow up a bubble so that it becomes thicker than what you see with the naked eye, then it will no longer reflect any colors at all.
The more soap you use when washing your hands, the smaller the bubbles will be and the less likely they are to be colored. This is because soap eats away at the surface of the water causing it to become more turbulent and thus reducing the amount of light that can get through to the layer beneath. If there is not enough light getting through, then none of the colors of light will reach the layer below and therefore no color will be reflected back towards your eye.
Why are soap bubbles so brightly colored? A soap bubble's hues are derived from white light, which contains all of the colors of the rainbow. When white light bounces off soap film, some colors get brighter while others fade away. White light is made up of light waves with a wide range of frequencies. When these waves hit the soap film, some waves go right through it while others are reflected back into our eyes, giving rise to the colors we see.
The colors of soap bubbles are very similar to those of rainbows. This is because when light waves of different colors reach the surface of soap film or water, they combine to form new waves with different properties. For example, red waves will cause any particles in the liquid to scatter red light while blue waves do the same thing to blue light. As these new waves bounce around inside the film or water, some waves will be reflected back towards our eyes and seen by us as colors in a bubble or in a rainbow.
Soap bubbles are colored by two types of scatterers: particles that reflect only certain colors of light and molecules that absorb certain colors completely.
Bubbles are drawn toward bright lights and thrown at high speeds against solid objects. If they hit your eye, they can cause serious injury. The force of the impact breaks the bubble into many tiny droplets that are carried by the wind away from the spot where it broke.
When light waves strike bubbles, part of the light is reflected back to your eyes from the bubble's outer surface. Some light is also reflected back to your eyes from the inner surface, which is only a millionth of an inch distant. As a result, bubbles might appear to change colors as they float around. This is because light waves of different colors reach them at different times.
Bubbles can be either natural or man-made. Natural bubbles are formed when liquid vaporizes and then collapses, such as when water evaporates after it has rained or when air bubbles rise to the top of a lake and then collapse. Man-made bubbles are created by forcing air into a liquid with a pump. The pressure inside the container increases, causing some of the liquid to vaporize without escaping through the open top. The gas inside the bubble is now under greater tension than the surrounding liquid, so it expands to fill its new volume.
Rainbows are produced when light from the Sun passes through layers of atmosphere containing particles with different sizes and shapes, such as clouds and water droplets. The particles refract (or bend) the light in various ways, creating colors at different distances from the source. If you were to walk outside during sunset and look up at the sky, you would see the rainbow arc formed by the color of sky at different heights above you.
The two sets of waves that return to your eyes conflict with one another. Some of the waves combine to make particular hues more vibrant. Others don't match up and are lost in a haze of color.
Bubbles reflect only certain parts of the light that reaches them. The colors you see in bubbles are determined by the chemicals inside the bubbles. When you look at blue bubbles, for example, the blue pigment inside the bubble prevents red and yellow waves from mixing together to make orange or green waves. Only blue waves reach your eye.
The color of bubbles is also affected by their size. Larger bubbles let more light through than small ones do. This is because larger bubbles have wider gaps between themselves and other objects. Light can pass through these gaps without being blocked by any other object.
Finally, the color of bubbles is influenced by how tightly they're packed. Packed very close together, bubbles become transparent. That is, you can see through them to the things behind them. Packed quite far apart, the effect is exactly opposite: They block out most of the light that reaches them.
So all things considered, yes, bubbles do reflect light.
