Sun radiation facts

 

The Sun Lights

 

The actual color of sun's light is white. When astronauts see the sun from space its look white.

Why its looks like white, because its light is not scattered by atmosphere.

And white color is mixture of seven colors called VIBGYOR.

But we can not see all color by our naked eyes, to watch VIBGYOR we will have to pass the sun's light through Prism or water's drops.

But there are some animals who can see all color of VIBGYOR as well as ultraviolet lights also with their naked eyes. e.g, honey bees can see ultraviolet lights, Pit viper can see infrared, Puppies, meanwhile can see into our heart, frogs can detect very sensitive photons.

Why leafs looks green, because leafs reflects only green color from VIBGYOR, and absorbed left all colors.

Lets know about Light.

Study of light is called optic.

Light travels in straight path

Light has electromagnetic energy.

Generally there are two type of light, (a) Visible light (b) Invisible light.

When we talk about visible light is known as light or optic. e.g, Sun light.

When we talk about invisible light is called electromagnetic radiation,  e.g, ultraviolet radiation

Light is made by very tiny packets called photon.

Every photons contain lots of energy.

Speed of light changes with change of mediums (objects or materials).

Lets know about Shadows.

99.99% Space is dark (full of shadows).

Because there is no sufficient light, light is visible when it has an object in its path.

No one has seen the shadow of moon, sun, Jupiter, mars, earth, Venus etc in space.

There is no shadow of astronauts has found in moon.

In ancient time people was thinking about shadow formed by sun, thought lot and utilized this principle in making the world’s most primitive clocks, the sundials.
