Why the sky is blue and sunsets turn it red ??

 The sky does not have a colour of its own  !!!

When sunlight enters the atmosphere, tiny gas molecules scatter blue wavelength of light strongly than other colours.

This scattered blue light comes from all directions, our eyes perceive the sky as blue  !!!

Although violet light scatters  more strongly than blue light, our eyes are more sensitive to blue light.

That's why sky looks blue.

When the Sun is high on the sky ,  sunlight travels a shorter distance through the atmosphere before reaching our eyes.

These continue travelling through atmosphere and reach our eyes.

But when the Sun is near the horizon like early in the morning or later in the evening, sunlight must pass through a much thicker layer of air..

At this point, most of violet and blue light are scattered away from our eyesight.

What is remaining is longer wavelength of light i. e. reds, oranges and yelows  !!!

Result  :

Colours of the sky are not coming from Sun itself, but from Earth's atmosphere  !!!

Bheja Fry question

 Question

The ratio between father and son age is 17 : 7.

6 years ago,  the ratio was 3  : 1.

What is the current age of father and son  ?? 

Answer

It is given that present age ratio of father and son is 17 :  7.

Let the age of father  17x

Age of son  7x

It is also given that 6 years ago, the ratio of their age was  7 :  1

Let the age 6 years ago, 

Father  17x  - 6

Son         7x  - 6

. 

Their age ratio  3 :  1

( 17 x  -  6 )  :  (  7 x  - 6  )  =   3 : 1

17 x  - 6              3

--------------     =   -----

7 x  -  6                1

Cross multiplying we get

17  x  -  6  =  3  (  7 x  -  6  ) 

17  x  -   6   =   21  x   -   18

21 x  -  17  x   =  - 6  + 18

4 x  =  12

X  =   3

At present, 

Son's age is   7 x  =  7  ×  3  =  21  years

Father's age is   17  x =  17  ×   3  =  51  years
