The term that describes substances that absorb some wavelengths of light is "pigment." Pigments can selectively absorb specific wavelengths while reflecting or transmitting others, which gives them their characteristic colors. They play crucial roles in processes such as photosynthesis in plants and are also used in various applications, including paints and dyes.
What else can I help you with?
Why grow lights for house plants are never green?
first off, plants are green meaning they dont absorb green wavelengths, they reflect it off which is what we see. secondly they need yellow/red colored light in order to perform photosynthesis since they absorb those colors. the sun viewed through our atmosphere appears yellow, not green.
Why is n2o3 colored?
Because its molecules contain differences between occupied and unoccupied energy levels of electrons that correspond in energy to part of the visible light spectrum. This causes the gas to absorb a noticeable fraction of some wavelenghts of visible lights while being transparent to others. The unabsorbed wavelengths of light correspond to the color of the gas.
Does white poster board reflect all lights?
Generally, white poster board reflects most visible lights. However, it may not reflect all lights equally. Some colors or wavelengths of light may be absorbed or scattered more than others, resulting in a slight variation in reflection.
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.
Which basic property determines a colored lights placement on the spectrum of visible light?
Most of the spectrum charts that I have seen are listed in wavelengths, particularly nanometers (nm). Where 1 nm = 1x10^-9 m.
Which term describes substances that absorb some wavelengths of light?
Pigment is a substance that absorbs some wavelengths of lights and reflects other, giving something its color. Chlorophyll is the green substance that absorbs light and provide energy for photosynthesis.
What term describes substances that absorb some wavelenghts of lights?
The term is "pigments." Pigments are substances that selectively absorb certain wavelengths of light and reflect others, giving them their characteristic color appearance.
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.
Can plants really go through photosynthesis as long as the spectrum part of the artificial light has wavelengths that the chlorophyll can grab?
Yes, plants can undergo photosynthesis as long as the artificial light source provides wavelengths of light that chlorophyll can absorb. Chlorophyll predominantly absorbs blue and red lights for photosynthesis, so ensuring these wavelengths are present will support plant growth and photosynthesis under artificial light.
What colour would the grass appear under orange lights and why?
The grass would appear black under orange lights because green objects appear black under light that does not include green wavelengths. Orange lights contain little to no green light, causing green objects like grass to absorb most of the light and appear as black.
Why grow lights for house plants are never green?
first off, plants are green meaning they dont absorb green wavelengths, they reflect it off which is what we see. secondly they need yellow/red colored light in order to perform photosynthesis since they absorb those colors. the sun viewed through our atmosphere appears yellow, not green.
Why does photodegradation occur?
The ability of degradable molecules to absorb lights wavw
What is the range of wavelengths for vsible lights?
from 400 manometers till 700-750 manometer.
Do blue lights attract bugs?
Yes, blue lights can attract bugs because many insects are drawn to certain wavelengths of light, including blue.
Is color a characteristic of visible light that does not depend on the lights wavelength?
Different wavelengths of light have different colors.
What best describes the approach lights?
Extend 1,000 ft from the runway centerline from threshold/End lights to the Strobe.
How do wavelengths of visible lights relate to energy?
The shorter the wavelength (blue rather than red), the higher the energy.
