Q5 of 8 Page 117

The telescope ‘Chandra’ is placed in the space. What is the advantage of placing it there? Explain with reference to the scattering of light in the atmosphere.

Scattering of light is the phenomena in which light is irregularly or partially reflected by very small particles into different direction.

In simple words it is like a collision between light particles and very small atmospheric particles {which has size compared to the wavelength of the light}; the collision results in the particular colour of the particles according to their size.


Now, when we want to observe outer space and the celestial bodies present in it, we observe the light coming from them and determine their different properties. But due to atmospheric particles the light coming from those celestial bodies got scattered and destroy all the information. We cannot determine any properties because of atmospheric scattering.


So, to solve this atmospheric scattering problem the satellite Chandra is placed into space which almost neglect all the scattering and will give us useful information. For this main advantage the satellite Chandra is placed into space.
