The Solar System part2

THE SOLAR SYSTEM (Part2)

When we talk about the Solar System ( solar family ), many people "specially students and kids" things that, what the exact mean of the solar system because it is a name which has combination of two words, ( SOLAR + SYSTEM ). Yes this is absolutely right solar system made by two words, First is SOLAR and second is SYSTEM. Come on

Order of all 8 planets from sun

let's to know what the exact mean it has. first of all we should divide it into two parts, first part is SOLAR and second part is SYSTEM. The exact meaning of first term "SOLAR" is  SUN, and the exact meaning of the second term "SYSTEM" is a GROUP OF OBJECTS in specific area ( around the Sun ).

After combining this two words, now we can define the Solar System easily, that is, The Solar System is a collection of objects which interact/connect to one another, and each object interact/connect with sun by the fundamental interaction. And the Sun is like as the Parent of the Solar System, and it controls all systems.

Meaning of collection of objects;

( In specific area around the Sun.....all planets, all moons, all comets, all asteroids, all minor planets, all dwarf planets, all satellites, and many hidden objects )

Visible light definition and energy

The Light energy

 

We can not see the energy by our naked eyes except one type of energy known as sun light,  this is the only type of energy which is visible for human eyes. But other animals can see hidden part of lights.

 

The beam of light, actually it is mix up of different colors, that why every colors has different wavelength to other. Some has longest wavelength some has shortest wavelength.

 

Sun is the biggest source of light energy. While is millions of mile far from us, it emits huge amount of light energy.

 

The fastest things on this earth is speed of light, which travels 300000 km/s in air.  This is faster than the speed of anything else! But speed of light is not same every where, it began to change during change of mediums. The speed fasted speed of light are, vacuum> air> water> glass> and so on.

 

All things ( all living things, human, animals, fishes, trees, rivers, mountains, etc) which are surviving on this planet cant be survive without sun light.

 

Trees absorb light energy from sun, convert it into making  their food, Humans and animals would be unable to see anything without light energy.

  Other source of light are street bulb or home bulb and fire, torch.

ABOUT  SHADOWS

Shadows are nothings, but it just black images of every opaque body made by stopping lights to pass through it.

 

Opaque objects is define as, all those object are said to be an opaque object  from which no light can pass through it. e.g, tree, book, table, home, umbrella, car etc.

 

There are no fix shape and size of shadow of any opaque object, shadows can change their shape and size place to place, time to time. But we know that an opaque object cant change their shape and size during time or place change.

 

Do you know why size and shape of shadows change? The size and shape of the shadow depends on the angle at which the light is falling on the object. 

 

Our shadow keeps changing in whole day. In the early morning  it will be the longest and, when the sun is overhead there is little or no shadow at all. Why? The position of sun changes throughout the day, thus changing the angle at which the rays fall on the ground.In ancient time people tracked the length of shadows throughout the day to keep track of time. The world’s earliest clock was a sun clock.

 

But one thing is amazing that the color of every opaque objects shadows are same, weather object is colorful or plane or have one color only. All have the same color of shadow that is dark (colorless).
