37. We all have seen the airplanes flying in the sky but might have not thought of how they actually
reach the correct destination. Air Traffic Control (ATC) is a service provided by ground-based
air traffic controllers who direct aircraft on the ground and through a given section of controlled
airspace, and can provide advisory services to aircraft in non-controlled airspace. Actually, all
this air traffic is managed and regulated by using various concepts based on coordinate
geometry and trigonometry.
At a given instance, ATC finds that the angle of elevation of an airplane from a point on the
ground is 60°. After a flight of 30 seconds, it is observed that the angle of elevation changes to
30°. The height of the plane remains constantly as 3000√3 m. Use the above information to

Dispersion of light occurs when white light is separated into its different constituent colors
because of refraction and Snell's law.
From Snell's law it can be seen that the angle of refraction of light in a prism depends on the
refractive index of the prism material.
Since the refractive index varies with wavelength, the angle that the light is refracted by will
also vary with wavelength, causing an angular separation of the colors known as angular
dispersion.
For visible light, refraction indices n of most transparent materials (e.g., air, glasses) decrease
with increasing wavelength l:
Colour Wavelength Crown Flint
(nm) glass glass
Violet 396.9 1.533 1.663
Blue 486.1 1.523 1.639
Yellow 589.3 1.517 1.627

Print and Censorship
The power of the printed word is most often seen in the way governments seek to regulate and
suppress print. The colonial government kept continuous track of all books and newspapers
published in India and passed numerous laws to control the press.
During the First World War, under the Defense of India Rules, 22 newspapers had to furnish
securities. Of these, 18 shut down rather than comply with government orders. The Sedition
Committee Report under Rowlatt in 1919 further strengthened controls that led to imposition of
penalties on various newspapers. At the outbreak of the Second World War, the Defense of
India Act was passed, allowing censoring of reports of war-related topics. All reports about the
Quit India Movement came under its purview. In August 1942, about 90 newspapers were
suppressed.

Linguistic diversity of India

answer depends on how one counts it. The latest
information that we have is from the Census of India
held in 2011. This census recorded more than 1300

Chhattisgarhi, Rajasthani and many others were
