Why is red light scattered the least

Answered By: Samuel Rivera Date: created: Oct 21 2021

When light enters the atmosphere, it is scattered by small air particles. The scattering of light is inversely proportional to the fourth power of its wavelength. As the red light has the highest wavelength among all the colours in the visible light, it is scattered the least.

Why is the Colour of sky blue

Answered By: Sean Green Date: created: Jan 01 2022

Why are traffic signals red in Class 10

Answered By: Raymond Wright Date: created: Sep 20 2022

In traffic signals red colour light is used to stop vehicles because it is having longer wave length. The colour which is having longer wavelength will undergo lesser scattering, hence it is visible from a longer distance. … So red light is able to travel the longest distance through fog, rain, and the alike.

Asked By: Noah Gray Date: created: Oct 19 2021

Why the danger signal is always red in Colour

Answered By: Jacob Bailey Date: created: Oct 21 2021
