Question

why is sky blue??.... what gives it blue colour??​

Answer 1

Answer:

IT IS DUE TO SCATTERING OF LIGHT

Explanation:

1. PARTICLES PRESENT IN THE AIR ARE VERY TINY SUCH AS THE DUST PARTICLES ETC..
2. THESE ARE VERY EFECTIVE  IN SCATTERING LIGHT OF SHORTER WAVELENGTH THAN OF LONGER WAVELENGTH

 TO UNDERSTAND MORE EFFECTIVELY,KNOW THIS LAW

RAYLEIGH LAW OF SCATTERING

THE AMOUNT OF LIGHT SCATTERED IS INVERSELY PROPORTIONAL TO THE FOURTH POWER OF ITS WAVELENGTH

    3. THEREFORE , SINCE BLUE COLOUR OF THE SUNLIGHT [WHITE    SPECTRUM] HAS SHORTER AND MEDIATE WAVELENGTH, IT IS SCATTERED MORE EFFECTIVELY THAN OTHERS .

THEREFORE SCATTERED BLUE LIGHT RECEIVED BY OUR EYES MAKES THE SKY APPEAR TO  BE BLUE
