How much of the electromagnetic spectrum is occupied by visible light?
Between 400nm and 700nm
What are the waves of visible light?
Anything from 700nm (red)-400nm (violet) is the visible light spectrum.
What is the frequency of all 7 electromagnetic waves in order?
radio wave 30cm> microwave 1nm-30cm infrared 700nm-1nm visible light 400nm-700nm the only wave that can be seen by human eyes ultraviolet 60nm-400nm x rays 0.001nm-60nm gamma rays >0.1nm
What are the wavelength limits for visible spectrum?
The range of visible spectrum is 400nm(Violet) to 700nm(Red).. (1nm = 10-9m)
Do light wave frequencies determine what color you see?
No, the wavelength determines the color of the light. 700nm corresponds to red, 400nm to about purple, and in between are the rest of the visible colours.
Seven forms of electromagnetic radiation?
The seven forms of electromagnetic radiation are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each form has different wavelengths and energies, which determine their respective uses and effects on matter.
What kind of wavelenght is visible light?
Their wave length is long, since you can see it, that means that the waves will move slower and have a longer length.
What range of wavelengths does UV radiation have?
Visible light has a wavelength of 400nm-700nm (from violet to red). Ultraviolet rays which starts immediately after the violet region of visible light have their wavelength from 10nm-400nm.(where nm means nano-meter)
Why can you see light waves but not other electromagnectic waves?
Our eyes only perceive electromagnetic radiation within approximately 700nm to 400nm (the range of visible light) as light. That's the way our eyes are biologically coded.
What are the 7 types of light waves in order?
radio wave 30cm> microwave 1nm-30cm infrared 700nm-1nm visible light 400nm-700nm the only wave that can be seen by human eyes ultraviolet 60nm-400nm x rays 0.001nm-60nm gamma rays >0.1nm
Is there a color or colors that no one ever seen and why is that?
Yes , there may be , because human visible range is between 400nm to 700nm wave length of spectrum,if we change our visible range then we can observe several new colors, but question is how.
What is a photosytem?
Chloroplasts can only absorb certain wavelengths of light because of the pigments they contain. There are 2 photosystems in plants called photosystem I and II. PS I absorbs light on the wavelength of 700nm while PS II absorbs 680nm because of their utilization of chlorophyll A and B. These two frequencies are are known as the peak absorption points because they are the wavelength at which light is most strongly absorbed. Different forms of chlorophyll and other photosynthetic pigments absorb other other frequencies of light but PS I and PS II are what is used for synthesizing ATP and reducing power which plants use to grow. The visible spectrum of light is between 380-750nm for humans. Therefore PS I and II require red light to perform photosynthesis. As stated before, however, there are other photosynthetic pigments present in plants and other phototrophic species such as bacteria and algae that absorb other pigments. An example of this is the carotenoid pigment that absorbs primarily blue light as do chlorophyll A and B. Blue light contains more energy than red light but for PS I and II and plant growth both are needed.
