Describe absorbtion and scattering of light?
Tyndall effect
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
Which type of spectrum is associated with the radiation of most stars?
absorption spectrum
What is the term for the way a mineral reflects light?
That would be the degree of luster.
What is the electromagentic spectrum?
The electromagnetic spectrum is the all the frequencies possible outiside of the visible spectrum such as ultraviolet.
What layer of the sun is responsible for the absorption of lines in the solar spectrum?
Light coming up from the centre of the Sun goes through the outer layer where it encounters absorbtion by elements in the outer layer, and this gives rise to absorbtion lines in the spectrum.
Image of emission or absorption spectrum of manganese?
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.
What is white color produced of?
White is technically the reflection of all colours on the spectrum while black is all colours' absorbtion.
Why does a gas give off an emission spectrum when it absorbs energy?
It doesn't. An absorbtion spectrum is produced when it absorbs energy. An emission spectrum is produced when it lets the energy go again. The energy changes are associated with the element's electrons going up to higher energy levels and then dropping down again.
How do you determine the composition of a new star that is located outside the solar system and inside our galaxy?
By looking at the spectrum of its light and finding out which absorbtion lines can be seen. The lines correspond to specific elements in the outer parts of the star.
Why is it important for a solar cell to reflect as little light as possible?
Less reflection, more absorbtion. More absorbtion, greater efficiency.
Why digestion is not completed inside your stomach?
Absorbtion
What is the opposite of laxative?
absorbtion Cork antidiarrhoeal
Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
What in the world does radar measure in the ocean?
light absorbtion
What is the slow burning of food in the body called?
absorbtion
What is the site of most digestion and absorbtion?
small intestine
