Question

Write any two natural phenomena taking place due to dispersion of light

Answer 1

Answer:

The two phenomenon are Blue sky and red sky

Answer 2

Natural phenomena that take place due to the dispersion of light are rainbow and blue sky.

Explanation:

• Dispersion of light is the phenomenon when white light passes through the glass prism it splits into seven constituent colours which are violet, indigo, blue, green, yellow, orange, and red.
• Rainbow is the result of dispersion of light by a water droplet and internal reflection which takes place inside the water droplets which acts as a glass prism.
• The dispersion of light by gasses and water droplets which are at different pressure in the atmosphere is the reason for the colour of the sky as blue.
• Atmosphere plays the main role in the scattering of light. when sunlight passes through the atmosphere, the fine particles in the air scatter blue colour more than red colour.
• Because the wavelength of blue is shorter than red colour.
