Artists michaelangelo, raphael, and leonardo da vinci belong to which period of the renaissance?
a. early renaissance
b. high renaissance
c. late renaissance

The correct answer is option B, High Renaissance

Explanation:

The high renaissance period is the first half of the 16th century which marked its beginning from 1490s and ended by late 15th century. Some of the best known artist of this period were Michelangelo, Raphael, Bramante, Leonardo da Vinci etc. The period of existence of these artist was  

a)Leobardo Da Vinci - 1452-1519

b)Michelangelo  - 1475-1564

c)Raphael – 1483 -1520

The correct answer is option B, High Renaissance

Explanation:

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
