What else can I help you with?
Does chlorophyll a absorb mostly orange-red and violet blue light?
actually plants are green to the human eye because they reflect green light witch in return your eyes absorb so the chlorophyll absorbs the red and the blue while reflecting the green spectrum. btw the plants absorb more blue light than red as blue light contains more energy than red due to the higher Frequency and therefor more energy.
What wavelength of light does chlorophyll a reflect?
There are 2 different types of chlorophyll. Chlorophyll "a" absorbs light in the violet and red regions of the visible spectrum while chlorophyll "b" absorbs light in the blue and red regions of the visible spectrum.
Why do plants have pigments?
Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. The reason that there are so many pigments is that each absorbs light more efficiently in a different part of the spectrum. Chlorophyll a absorbs well at a wavelength of about 400-450 nm and at 650-700 nm; chlorophyll b at 450-500 nm and at 600-650 nm. Xanthophyll absorbs well at 400-530 nm. However, none of the pigments absorbs well in the green-yellow region, which is responsible for the abundant green we see in nature.
How many absorption peaks does chlorophyll a have?
Chlorophyll a has two absorption peaks in the visible spectrum, at around 430 nm and 660 nm. These peaks correspond to the blue and red regions of the light spectrum, which are most important for photosynthesis.
Do human photoreceptors respond to light in the 100-300 nm range?
No, human photoreceptors do not respond to light in the 100-300 nm range. The visible light spectrum for humans ranges from approximately 400-700 nm, with shorter wavelengths being ultraviolet light that is not detected by our visual system.
In what region of the electromagnetic spectrum does 230 nm of light lie?
230 nm of light lies in the ultraviolet region of the electromagnetic spectrum.
What part of the electromagnetic spectrum that you can see is called?
It is called the visible spectrum, and includes electromagnetic waves with wavelengths from 390 nm to 750 nm.
Where does visible light fall on electromagnetic spectrum?
Visible light falls between the wavelengths of 380 nm and 760 nm in the electromagnetic spectrum.
What wavelength does chlorophyll a absorb the most energy?
Chlorophyll a absorbs the most energy in the red and blue-violet regions of the electromagnetic spectrum, around 430 nm and 662 nm respectively. These wavelengths are most effective for driving the photosynthetic process in plants.
Light 489 nm Where is this on the electromagnetic spectrum If it is visible light what color Another laser a diode laser emits light 987 nm Where is this on the electromagnetic spectrum?
Light with a wavelength of 489 nm falls within the blue region of the visible spectrum. It is part of the visible light spectrum. Light with a wavelength of 987 nm falls within the infrared region of the electromagnetic spectrum.
The part of the electromagnetic spectrum that you can see?
visible light790-400 nm
What is the name of the region of the electromagnetic spectrum that is found between the wavelengths of 400 and 700 nm?
The region of the electromagnetic spectrum between 400 and 700 nm is known as the visible light spectrum. This is the range of wavelengths that the human eye can perceive, which includes the colors of the rainbow.
What waves on a electromagnetic spectrum do you see?
The oft quoted human vision spectrum is wavelengths from 390 to 750 nm
What happens to the wavelengths of light As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum?
It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm
The visible portion of the electromagnetic spectrum extends from what?
From Red about 780 nm (380 THz) to Violet about 400 nm (750 THz)
What wavelengths of light does chorophyll a asborb best?
Chlorophyll a primarily absorbs light in the blue (450-480 nm) and red (650-700 nm) regions of the electromagnetic spectrum. This absorption allows chlorophyll a to participate in photosynthesis, converting light energy into chemical energy for the plant.
What is the portion of the electromagnetic spectrum visible to the human eye?
We refer to this portion as "visible light," which has wavelengths between 390 nm and 700 nm.
