Why is the sky blue? Why is the grass green?

 

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

 

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

 

 

Grass appears green because all of the colors in the rainbow are absorbed into the leaves of the grass except green.

Why do stars shine?

Answer: Stars get their heat from two sources - gravity, and

nuclear fusion. When stars initially form from large balls

of gas, they contract under the influence of gravity, and

heat up because that gravitational energy goes into the

motion of the gas. Once they get hot enough, the hydrogen

nuclei in the plasma in the center of the star start to

occasionally merge to form helium, releasing a lot of energy

from that nuclear fusion process. All this heating, from

both sources, creates a pressure that causes the star to

quit contracting at some point. If the star is big enough to

start with, the central temperature will be high enough to

really keep that fusion going, and the heat gradually will

seep out to the outside parts of the star, so the outer

surface regions will also rise to quite high temperatures.

It is the temperature of the outer surface that determines the

way the stars shine - our sun has an outer temperature of around

5000 degrees, but other stars can be as hot as 50,000 degrees,

producing much bluer light, while red dwarf stars are considerably

cooler and produce mostly red and infrared light.

yeah, chlorophyll pigments in chloroplasts reflect the green wavelength..

CHAV-"The word Chav is thought to be from the mid-19th century Romany word chavi, meaning child. Others suggest it originates from a nickname used of people from the town of Chatham. It is sometimes mockingly redefined as an acronym of "Council Housed And Violent", or "Council House Assault & Violence", although there is no etymological basis for this — it is likely to be a backronym."

 

Hope to be of some use.
