![]() If all of the light is reflected, we see all the wavelengths, which means we see white light.Ĭontinue to read about how light interacts with atoms. There is no reflected light, so we see black (the absence of color). Black objects absorb all the light shined on them. In each case we are seeing the complementary colors to the ones absorbed.īy looking at the absorption spectrum and complementary colors for chlorophyll we should be able to predict that plants look green.īlack and white objects are just the extremes of colored objects. When sunlight is shined on a green leaf, the violet, red and orange wavelengths are absorbed. The transmitted light is the light we see, and it looks orange.Ĭolored objects look the way they do because of reflected light. When sunlight shines through an orange solution, the violet, blue and green wavelengths are absorbed. The test tube in the figure contains an orange solution. Objects like this are called blackbody radiators.Ĭolored liquids or solutions look colored because they absorb some of the light shined on them. Also known as ultra-violet photography, or UV photography, black light photography is a style of photography that excludes visible light, instead leveraging UV. It looks white because it is emitting at least some of all the wavelengths in the visible region. ![]() If someone shined white light at us, what wavelength does it have? White is not in our visible spectrum because it is composed of all the wavelengths of light. Violet is the most energetic color and red is the least.Īccording to the figure, if someone shined light with a wavelength of 550 nm at us it would look green. Note that these are in reverse order on the figure below. In Background, you can select a picture or solid color, or create a slideshow of pictures. The preview window gives you a sneak peek of your changes as you make them. The acronym "ROYGBIV" helps us to remember the colors of red, orange, yellow, green, blue, indigo and violet. Select Start > Settings > Personalization. The different wavelengths within the visible region are responsible for the different colors we see.
