Between 380 nm (visible as violet) to 750 nm (visible as red).
680 nanometers to 700 nanometers is about optimum for the photosynthetic rate but there are other wave lengths that plants do use.
Energy with shorter weve lengths, such as ultra violet, has higher energy levels than those with longer wave lengths, such as infrareds. So, I assume the portions of the visible spectrum with shorter wave lengths benefit photosynthesis the most.
he said that light consisted of different wavelengths and when it is passed through a prism the wave lengths get split up and form different colours
This is not a good question - x-ray IS radiation. It's just a specific type of radiation and longitude. But its very short - 10^-10 m (1 A). For example - the visible light spectrum is (more or less) from 400 to 800 nm (10^-9 m). That's why you cannot see x-rays.
Some of the sun's rays are ionizing and some not. The portion that is not ionizing is the visible spectrum, anything with longer wavelength (infrared), and a bit of the ultraviolet spectrum. The shorter wave lengths are all ionizing.
Ultra-violet light (wavelength approx 10-390 nanometers) lies between visible light (wavelength approx 390-750 nanometers) and X-rays (wavelength approx 0.1-10 nanometers).
Lengths - including wavelengths - are measured in meters. Of course, multiple or sub-multiples such as kilometers, nanometers, etc. may be used in practice.
Visible light wavelengths fill the electromagnetic spectrum between red wavelengths and violet wavelengths.
Nanometers are used to measure extremely small lengths or distances. For example, 25,400,000 nanometers is only 1 inch.
No black paper is not translucent ts opaque
There is no longest wave-length for light. It can be infinitely long (just as light waves could be infinitely short). The longest visible light that humans can see is about 750 nanometers long, which is 0.00075 of a millimeter. This color would be a shade of red. Some other animals and insects can see slightly longer wavelengths, and many can not even see what we can.
Some words that rhyme with "wavelengths" include "strengths," "lengths," and "trends."
680 nanometers to 700 nanometers is about optimum for the photosynthetic rate but there are other wave lengths that plants do use.
In general the resonant lengths are 1/4, 3/4, 5/4
Visible light contains all of the colors with in the spectrum. The only way we see color is the bending and refraction of the visible light sending certain wave lengths back, which our brain interprets as different colors.
Radio waves, microwaves and infrared light have a longer wavelength and lower frequency than visible light.
- Long wavelengths - Mid-size wavelengths - Short wavelengths The reddish colors are the long wavelengths, the mid-size wavelengths are the greenish colors and the short wavelengths are the bluish colors.
