1. Energy is supplied to the gasesous atomsfrom the hot gas or vapour sourse.
2. Infinite number of discrete energy level exist in the atomic structure
3. The atom are excited to upper enery level but wont reside at excited states for long and revert back to ground state
4. The electronic transition from high energy level to low energy level emits photon
5. The photon energy is equal the energy different between those two levels.
6. Series of distinct lines on dark background is formed

Can a spectrum be formed by reflection of white light?
No, but it can be formed by refraction.
What is main difference between prism spectrum and grating spectrum?
Prism spectrum is formed due to DISPERSION but grating spectrum is formed due to DIFFRACTION. In prism spectrum we have only one order but in grating spectrum we can have second order too IN prism spectrum we have continuous spectrum but in gratings we have only line spectrum In prism spectrum red end will be closer to the direct ray but in grating spectrum violet end will be closer to the direct ray
What is the series of colour bands that are formed after light passes through a prism called?
SPECTRUM
What colors do white paper reflect?
All of them. White light is formed by all the colours of the visible spectrum combined.
What is white light in a rainbow?
White light is formed by the joining of all the colours in the Rainbow i.e. it is a mix of all the 7 colours in the spectrum.
Can a spectrum be formed by reflection of white light?

What concepts explains how the rainbow is formed?
A Spectrum
How electromagnet spectrum was found?
Electromagnetic spectrum is formed due to the difference of wavelengths and frequency of electromagnetic radiations as they are orderly distributed.
Which type of spectrum can be produced by solid liquid or gas?
The spectrum produced by solid is continuous spectrum. Continuous spectrum is formed by all, solid liquid and gases if the pressure is high. In case of low pressure, gases produce line spectrum.
What type of light is formed when all of the lights of the visible spectrum combine?
White light contains all the colors of the visible spectrum.
What does the spectrum consists of?
a band of colors formed when white light passes through a prism.
A range of colors formed when white light passes through a prism is called a?
spectrum :)
What is the series of colour bands that are formed after light passes through a prism called?
SPECTRUM
Can you describe the wireless spectrum?
It is the set area of radio frequencies on which wireless communication is formed upon.
What colors do white paper reflect?
All of them. White light is formed by all the colours of the visible spectrum combined.
How is a spectrum formed on a CD?
That is caused by interference patterns between the light that rebounds from the different tiny holes and comes to our eyes.
