Light color does influence plant growth in several ways. However, it is
difficult for students to compare plant growth under different colored lights
because expensive equipment is required to assure that each treatment gets the
same amount of light and just the color is different. If this is not done, then
plant growth may be affected more by the different amount of light than the
color.
Some easier to set up plants and light experiments would be the following:
Examine the effect of light amount on plant growth. You can hang a 4 foot
fluorescent shop fixture at a 45 degree angle and get different amounts of light
from one end to the other.
Determine what color light is required for phototropism. This can be done with
red, green, and blue films and a black 35 mm film can. Punch holes in the middle
of the side of the film can at 120 degrees apart using a paper punch. Tape a
different colored film over each hole with transparent tape. Place some wet
paper towel squares on the film can lid and germinate a small seed, such as
Wisconsin Fast plant. Place the film can in a light location and see which
window the seedling bends toward. The control is a film can with no holes.
See if plant growth is better under special plant grow lights (such as Gro-Lux)
than with regular cool white fluorescent lamps. Use same wattage for each type.
Yes, different colored lights can have different effects on plant growth. For example, blue light promotes vegetative growth and is often used for seedlings, while red light stimulates flowering and fruiting. The overall spectrum of light (wavelengths) is crucial for optimal plant growth.
yess it does. Blue light helps plants grow faster.
Im sorry but i dont know why though.
Red light makes plants grow slightely faster and green light makes them a tiny bit faster.

Does lights with coloured cellophane affect the growth of food?
Coloured cellophane will filter out certain wavelengths of light, which may affect the growth of plants by limiting the spectrum of light available for photosynthesis. Different colors of light play a role in different stages of plant growth, so using only colored cellophane could potentially hinder the plant's ability to thrive.
When are colored lights used?
Colored lights are typically used for decorative purposes, like holiday displays or events. They can also be used in theatrical performances, concerts, or theme parks to create a specific atmosphere or mood. Additionally, colored lights can be used in traffic signals to indicate different instructions or warnings.
Why use grow lights instead of incandescent lights?
Grow lights are more efficient for plant growth because they emit specific wavelengths of light that are optimal for photosynthesis. Incandescent lights produce a lot of heat and not enough of the red and blue light that plants need, making them less effective for promoting plant growth. Additionally, grow lights are designed to provide a balance of light spectrums tailored to the different stages of plant growth.
When fireworks go off why do you see colored lights?
Fireworks produce colored lights through the use of different chemical compounds that burn at high temperatures, emitting specific wavelengths of light. Each color corresponds to a different chemical element used in the fireworks composition, such as strontium for red, barium for green, and copper for blue. The intensity and duration of the colored light depend on the type and amount of chemicals present in the fireworks.
Does a light bulb have an affect on plant growth?
Yes, light bulbs can affect plant growth by providing the necessary light spectrum for photosynthesis. Different plants require different levels of light intensity and spectrum, so it's important to choose the right type of light bulb for optimal growth. LED grow lights are popular for indoor gardening because they can provide the right spectrum of light needed for plant growth.
Why will different colered lights affect plants growth?
different colored lights have different energy required to kick an lectron out of its orbit in an electron transfer process inside the plant
Does lights with coloured cellophane affect the growth of food?

Does different colored lights do any effect on a weed plant?
no
Why colored lights are called additive colors?
Colored lights are called additive colors because when different colored lights are combined, they add up to create new colors through the process of light mixing. This is in contrast to subtractive colors, where different pigments absorb certain wavelengths of light, resulting in different colors when combined.
Does coloured bulbs change your behavior?
Different colored lights affect a persons mood more than anything. Whether the alteration in moods correspond to a change in behavior or not depends on the individual.
When are colored lights used?
Colored lights are typically used for decorative purposes, like holiday displays or events. They can also be used in theatrical performances, concerts, or theme parks to create a specific atmosphere or mood. Additionally, colored lights can be used in traffic signals to indicate different instructions or warnings.
Why do coloured objects look different coloured lights?
Colored objects absorb some colors of light and reflect others. When you shine a colored light on an object, the object will absorb the light colors it matches and reflect the colors that it does not. This interaction between the object's color and the light color leads to the object appearing to be a different color under different colored lights.
Where can one find colored lights online?
The LightInTheBox, LampsPlus, and LightingUniverse websites all sell colored lights online. Amazon and eBay also have colored lights for sale online.
What is the difference between mixing colored lights and mixing pigments?
Mixing colored lights involves adding different colored lights together to create a new color, while mixing pigments involves blending different colored powders or liquids together to create a new color. In mixing colored lights, the primary colors are red, green, and blue, while in mixing pigments, the primary colors are red, yellow, and blue. Mixing colored lights follows an additive color model, while mixing pigments follows a subtractive color model.
If you put 2 different colored light bulbs in your fish tank what will happen?
Your tank will have two coloured lights.
Can a bean grow with different color light?
Yes, beans can grow under different colored lights, but the type of light can affect the growth and development of the plant. Plants typically respond best to blue and red light wavelengths for photosynthesis and growth, while green light is less effective. It's important to provide the right balance of light colors for optimal bean growth.
When you mix colored lights you blank colors until you get white?
When you mix colored lights, you add colors until you get white. This is known as additive color mixing. By combining red, green, and blue light in different intensities, you can create white light because the three colors together cover the entire visible spectrum.
