Theory of light and color: Newton separated white light into its colors using a (a triangular geometric figure) and proved that consists of different colors.
• The corpuscular theory: Newton explained that light is made up of called corpuscles,
and they move in a line.
• Newton’s laws of motion: Newton investigated and .
• The theory of gravity: Newton explained that was the mutual of all
matter.

The diagram from Sir Isaac Newton's crucial experiment, 1666-72. A ray of light is divided into its constituent colors by the first prism (left), and the resulting bundle of colred rays is reconstituted into white light by the second. ... The violet is bent more than the yellow and red, so the colors separate.Newton's Corpuscular Theory Statement

According to the Newton's corpuscular theory: Light is made up of tiny particles called 'corpuscles' having negligible mass. These particles (corpuscles) are perfectly elastic. The corpuscles are emitted from the luminous sources such as Sun, candle, electric lamp etc.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
