How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
Why does a rainbow show colors from reds to violet?
There's a broad band of wavelengths of light coming from a rainbow. They range from wavelengths that are too short for your eyes to detect, all the way to wavelengths that are too long for your eyes to detect. Within that band of wavelengths is the total band that your eyes can detect, and you see them as a spread out display of all the colors that your eyes and brain can work together to perceive.
Why do different shaded rays come of the sun?
ALL visible light is made up of a superposition of different wavelengths. The light from the sun is no different.
How can astronomers detect structure in the suns chromosphere?
The structure of the chromosphere is studied primarily using filtergrams. Filtergrams are images of the sun taken through a filter that lets in a very narrow wavelength band of light, such as light emitted by the Hydrogen-alpha transition.
Explain how astronomers use electromagnetic radiation to study space?
Electromagnetic radiation is "light." Light in various wavelengths (gamma rays through to infrared) comes to us from out in space, and astronomers use instruments called telescopes to capture it and observe the bodies and processes emitting this light.
What wavelengths can astronomers detect from earth?
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
Is the rod sensitive to light?
Rods are sensitive to light and cones are sensitive to the different wavelengths of light. There are different pigments in the three different types of cones to detect red, green, and blue wavelengths of light. (referred to as trichromatic vision)
What can ocelli detect?
Tiny eyes (also called ocelli) that can detect light and dark are located on top of the spiders cephalothorax. They also can detect different wavelengths and intensities of light.
Why can wavelengths of light be seen by humans?
Our eyes can detect them.
Which wave can your eye detect?
If you mean, "which wavelengths of light can the human eye detect," the human eye can see wavelengths from about 390 to 700 nanometers.
Why is chromatic aberration a problem for astronomers?
When light of different wavelengths is scattered sightly due to differences in how the light reacts to the optics of the system. when light of different wavelengths are scattered slightly due to differences in how the light reacts to the optics of the system
What do humans see different wavelengths of as light?
Different wavelengths of visible light are different colors.
What is the separation of light into different wavelengths?
It means the wavelengths are separated. White light, for example, is actually a mixture of different wavelengths.
What is a Range of light of different colors and different wavelengths?
I believe that a range of light of different colors and different wavelengths is a spectrum.
How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
Why do you call the visible light part of the EMS visible light?
Because it's comprised of the band of wavelengths that the human eye can detect, that is, wavelengths that are 'visible' to human beings.
Light of different wavelengths is different colors?
Yes that is true. Different wavelengths means different colors. The amplitude of the wave determines how bright the light is.
