The light coming from the sun looks white but it is actually made up of all colors of the rainbow. Like energy passing through the ocean in the form of waves, light energy travels in waves too. Some colors of light travel in short waves, while others travel in long waves. The wavelength of long waves are more than the short waves, So Blue light wave has a shorter wavelength than Red light waves.
Thank you for reading this post, don't forget to subscribe!Light travels in a straight line unless some obstacles get in the way and do one of the following things:-
- Reflect it Eg. Mirror
- Bend it Eg – Prism
- Scatter it Eg. – Molecules of gases
All gases present in the atmosphere scattered Sunlight in all directions before it reaches Earth’s atmosphere. Blue light is scattered more in all directions by tiny molecules present in the air because it has a shorter wavelength, that is why we see a blue sky most of the time.
