Magenta appears to reflect from the soap bubble when the thickness of the film is such that green light is canceled.

NaHSO4 itself is acidic, so the solution's color should be yellow due to the bromcresol green being in the presence of acid

What colour will what be?\n\nLight is additive: red light plus green light will yield whitish light.  The blue object will still look blue.\n\nIf you mean that the light passes through the blue object onto the screen, all non-blue light will be filtered out, so the spot on the screen will look blue.

Yes, it would be black. The colour of object depends on what wavelengths of light are absorbed and which are reflected back by an object essentially.\n\nSo if all wavelengths of light are absorbed then it appears black, and if everything is reflected then it appears white. Every other colour we see depends again on the wavelength that is reflected.

Of course, sunlight is made up of many colors.  However, we can think about "original" (or "monochromatic", or more realistically nearly monochromatic) yellow lights from other sources (like a laser).\n\nWith the composed yellow, you can separate the green and the red back out.  One way to do this would be with a prism.  While the monochromatic yellow light would just stay yellow, the composed red+green would separate back out, with each color in its position in the rainbow.\n\nA more sophisticated way to do this would be with a spectrometer.  The monochromatic yellow would show just the one wavelength, in the yellow part of the spectrum.  The composed light would show two wavelengths: one each in the green and red parts of the spectrum.  It would show no light in the yellow part of the spectrum.\n\nSnawshia is right about the speed: in a vacuum, they'll have the same speed.  In other media (water, glass, etc.), each color may have a slightly different speed.

Any solid mass in the heavens has some reflective properties the same as here on earth.\nA white sheet will reflect more sunlight than a black (or dark colored) sheet. In reflecting more sunlight/energy, it absorbs more heat.  I'm sure you've felt this in dark colored cars in the summer or have watched dark road patches expand and melt quicker than the packed white snow on the same surface in the winter.\nWell, all solid bodies have a certain "color"; \nMars is red because of all the iron oxide (rust) on the surface (it has no cloud cover) and that is the reflected light that we see. \nVenus looks bright, not because of its surface, but because of the clouds in the atmosphere (alot of them in its sky) and it reflects alot of the sunlight.\nStars twinkle.\nPlanets do not twinkle.\nOur moon is covered with a fine dust, greyish, almost white in color and that is the reflected light that we see.\nIf you look at the sky during a new moon you can faintly see the very dark grey of the moon. This is the light that is reflected off the earth, which hits the moon and is reflected back to us (very faint).\nMr Giraffe...all objects are reflective, even dark ones. That's how we see them.\nWhite is the entire spectrum of visible light being reflected. It is a combination of all colors.\nBlack is the absence of color being reflected.\nWhen you see the color red, it is the red part of the spectrum that is being reflected from the object. All the other colors are being absorbed. So what you see is that which is not absorbed by the object, but refkected by it.\nAny questions?

This is due to the way we perceive objects.  When you look at something and see a color, you are merely seeing color being reflected back at you.  In theory, the sun (or lights in our houses) produce white light which consists of every color.  When white light hits an object, some of it reflects and some of it is absorbed.  In black objects, no light reflects and all of it is absorbed.  In white objects, all the light reflects and none is absorbed.  Similarly, the same is true about colored objects.  In red things, red light reflects and everything else is absorbed.  In blue objects, blue light reflects and everything else is absorbed.  Similarly with plants, the green leaves reflect green light and all the rest of white light (red, blue, orange, purple, etc) is absorbed and used as energy.  Specifically, it is the properties of chlorophyll A and chlorophyll B that cause this green reflection.  Oddly enough, in most plants there is some Betacarotine as well that reflects orange light.  There is just so much more chlorophyll that all we see is green.  However, in the fall when leaves start to die, the chlorophyll goes first and the betacarotine sticks around, causing the leaves to turn orange!\n\nHope this helps!

Stars emit their own bright light, so to our eyes it looks white. Moon reflects the sun rays, so the easiest colour of light absorbed and reflected is white. That is why.

Perceived colour is dependent on the light wavelengths being reflected back to your eyes. What's reflected changes according to depth, substrate (if it's shallow enough to see the substrate) turbidity (as in mud and organic junk and whatever else affecting the clarity of the water), biological content (i.e. high levels of phytoplankton can make water appear very green, and shallow tropical areas with very little plankton can appear bright blue, etc).

Sunlight from the Sun would have to reflect off something in space in order for that region of space not to appear black.  For example the Moon doesn't look black because Sunlight is reflecting off its surface.\n\nSpace is for the most part black since there is an absence of material that can produce or relfect light there.

Light from the Sun is reflected off of the Earth  onto the Moon. Some of this light is then reflected off of the Moon back towards the Earth.  Because of this we see part of the Moon illuminated by the Sun and the rest of the Moon dimly illuminated by this doubly reflected light (which we call earthshine). Each time light reflects off a surface (like a planet), it gets dimmer because some of the light is absorbed by the reflecting surface. This means that earthshine is dimmer than moonlight because earthshine is sunlight that has been reflected twice and moonlight is sunlight that has been reflected only once (off the surface of the moon). In addition, the reflectivity of the moon (its "albedo") is less than that of the Earth, which makes earthshine even dimmer. \n\nHave you ever wondered why the moon is more orange or yellow in color when it first rises at night? This effect is caused by the atmosphere of the earth. The reason for the orange color is due to the scattering of light by the atmosphere. When the moon is near the horizon, the moonlight must pass through much more atmosphere than when the moon is directly overhead. By the time the moonlight reaches your eyes, the blue, green, and purple pieces of visible light have been scattered away by air molecules. That's why you only see yellow, orange, or red.

hmmmm, my bubles have all the colors of the rainbow.\njust need to look closely. a beauty, those colors are slowly flowing over the surface of the bubble, ....then i pop the bubble, muahahahaha.

Probably because the dye that colors the soap is not a compound that froths and bubbles the same way soap does, if it does at all. It also might be spread out too much as the soap expands into bubbles to be seen clearly.

When sunlight hits the ocean it is scattered by the water molecules that make up the ocean. Sunlight is made up of all of the colors of the rainbow (red through violet). Water molecules scatter blue light the most. This makes the ocean look blue.\n\nThe reflection of the sky is a common misconception.  Algae and plankton also add color to the ocean as well.

light green and sky blue...

The light is reflected

It is because of the conjugate dienes. i.e. Double bond C single bond C double bonds. C=C-C=C etc. These conjugated dienes absorb light in the visible spectrum and in this case it happens to be pale yellow.
