Question

State whether the following statement is true or false:

Red coloured light has a longer wavelength but the blue coloured light has a shorter wavelength.

Answer 1

This statement is true.

Explanation:

Red light sits at the long-wavelength end of the visible spectrum (around 700 nanometers), meaning its waves are stretched out. Conversely, blue light sits at the short-wavelength end (around 400 nanometers) with highly compressed waves. Because of this structural difference, blue light carries more energy and scatters much more easily than red light when passing through Earth’s atmosphere.
