What some things which use light?
Most living organisms, you included, and of course, plants.
What instrument disperses light into its component wavelengths using a prism?
Component wavelengths are usually present in radio active decay in a form of light, but you could use an electric guitar, using the amp as a transformer of vibrations to electricity to vibration/ lights
How could you use the spot lights at a play to make the yellow clothes of the performers suddenly change to black?
You would have to use light at wavelengths that aren't reflected by the yellow fabric(or, since materials seldom reflect a single wavelength only, those wavelengths it reflects poorly). It would appear dark then.
For a substance to appear black and what must happen to all wavelengths of light?
A substance that appears black (in a lighted room) is absorbing all of the visible light that hits it, leaving no visible light to reflect off of it to your eye. So it's absorbing visible light of all wavelengths. (You still don't know what's happening to the infra-red or ultraviolet hitting it. For that, you need to use different detectors.)

What colors provide the most energy for plants?
The wavelengths of light that contain the most energy that plants can use are blue.
What wavelengths of visible light can plants use as a source of energy?
Most of the visible light spectrum except green wavelengths is absorbed by the chlorophyll molecule and is usable in photosynthesis as a source of energy for plants.
Why don't plants use UV rays for photosynthesis?
because the ozone in the earth's atmosphere absorbs most UV wavelengths, plants have evolved accordingly. while most pigments developed don't use UV light, some wavelengths are still converted into energy.
What green plants can use to make food because of chlorophyll?
Light in the blue and red wavelengths.
True or false When light hits a plant all of the wavelengths of light are absorbed by chlorophyll?
No. There are only certain wavelengths of light that plants can use for photosynthesis.Plants have trouble using green light because it is reflected by the chlorophyll pigment (that is why leaves look green).
Why is grass green in color?
All plants contain the molecule Chlorophyll which is used by most plants in the process of photosynthesis. This Chlorophyll molecule absorbs Red and Blue light to use the energy from these wavelengths leaving green light to be reflected. It is this reflected green light that makes the leaves of plants look green.
Why is it that generally the leaves of plants is color green?
Because plants use chlorophyll to photosynthesize energy from solar radiation and chlorophyll is a bad absorber of light's green wavelengths.
What are are some light experiments?
A good experiment with light would be to use different wavelengths and to see which ones the chlorophyll reacts to the most actively.
What part of the electromagnetic spectrum do the chloroplasts use?
Chloroplasts of different plants absorb different wavelengths, but usually regions within the Visible light band are used.
What is the most important product of the light reaction in plants for humans?
Plants use light to produce oxygen which we breath.
What is the difference between primary pigment and accessory pigment?
The main difference is the wavelengths of light that they absorb and reflect, this allows plants to make use of more wavelengths of light. Primary pigments also create electrons directly, however I can't seem to find what the accessory pigments do instead...anyways, hope that helps
What color of light would probably be the least helpful for this plant's growth?
White light would be universal, but if you had to choose a color, and the color of the plant is green, then green light would not help it photosynthesize the easiest, because green light is reflected from these plants. Just like red light would be reflected from red plants, it probably wouldn't be the best to use
