WHY THE SUNSET COLOUR IS RED?

 

 

 You know  when SUNSET it's colourget change. 

But which  change ?

Now, we will learn about  this.

My first question 

What gives sky  its colour?

 There are three components 

1.SUN

2. EARTH  ATMOSPHERE 

3. HUMAN EYE 

The earth atmosphere  and human eyes are major role in colour  changing  on sun. 

NOW EACH COLOUR  HAVE OWN WAVELENGTH 

 Like 

NM= NANO METER

 COLOUR                 —                 WAVELENGTH

 

1. RED                      —                665 NM

2. ORANGE             —                 630NM

3. YELLOW         —           600NM 

4.GREEN                 —                 500NM

5.BLUE                    —                  470NM

 6. INDIGO             —                  425NM 

7. VIOLET                —                   400NM  

 

Now the different  colours are enter to the atmosphere. 

There are different  types of   molecules of gas in the atmosphere of nitrogen,  oxygen a Budden.

 The molecules cule act like a obstacles  other 7 colours.

 

The shorter WAVELENGTH  colour get scattered  like violet , indigo, blue.

But

The longer WAVELENGTH  colour less  like

Red,yellow,orange. 

NOW WHY WE SEE BLUE SKY?

BECAUSE  OUR EYES CONES CELL ARE MORE SENSITIVE TO BLUE COLOUR THEN THEY ARE TO VIOLET OR INDIGO.

NOW MY FIRST QUESTION 

Why does  the sky change colour sunset?

At sunset the sun rays have to  travel more distance to the  many atmosphere  in the  sky.
