Why is it that different light sources have different types of spectra?
Different atoms have a different number of electrons. This is why they show different spectra.
Why do stellar spectra have absorption lines?
Need a different, better answer.
What is the name of the spectrum when elements produce different colors when heated?
Atomic spectra
What spectra are used to analyze stars?
The spectra of the stars you want to analyze.
What is the frequency of color?
Every color has a different frequency. That's why it appears to our eyes as a different color.
Why did each compound produce a flame of a different color?
Different elements have different emission spectra, meaning that if the electrons in an atom are excited, they will release that energy in different color of light. The flame color depends on the elements in the compound.
What is extinction spectra?
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.
How do different scientists spectra to figure out the composition of a star's outer layer?
The color of the light radiated by the spectra can show the internal composition as well as the gases burning on the outer layer. Red stars are colder and blue stars are hotter.
Why is it that different light sources have different types of spectra?
Different atoms have a different number of electrons. This is why they show different spectra.
What is the difference between the different polaroid spectra cameras?
The best place for information on the Polaroid Spectra cameras is camerapedia.org.
What is the difference between the spectra of different gas tubes?
They have different packaged particles.
What kind of interiors are offered on the latest Kia Spectra models?
The Kia Spectra comes in gray, black and beige interior colors. Carsdirect.com offers a combination color key here, http://www.carsdirect.com/kia/spectra/colors.
How can you make one light bulb change different colors automatically with wiring?
A normal incandescent or fluorescent lamps can not change colors. Even an LED can not change color. But an LED can be designed to have a certain color. Color changing LED is actually a combination of of three LEDs encapsulated in one casing. By turning the LED on or off a combination of colors can be achieved.
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
Why do stellar spectra have absorption lines?
Need a different, better answer.
How are different types types of spectra created?
The different types of spectra are created by light shining through a prism, a glowing solid or liquid, or by a compressed/non-compressed glowing glass.
How do Spectra from neutral atoms compared with spectra from ionized atoms of the same element?
have different sets of spectral lines. :) u got to love astronomy
