Yes, purple lightning is real. While lightning is most often seen as white or yellow, purple is actually the most common color.
The Science Behind Purple Lightning
The color of lightning depends on several atmospheric conditions. These conditions affect how light is scattered and absorbed as the electrical discharge travels through the air. The statement "Lightning can appear many different colours, but purple is the most common" directly addresses this. A combination of factors determines the final observed color.
- Atmospheric Composition: The gases and particles present in the air influence light scattering and absorption.
- Distance: The distance between the observer and the lightning strike also affects perceived color.
Although less frequently seen than purple, other colors, such as red, blue, and green, are also possible. These variations result from interactions of the electrical discharge with different atmospheric components at varying altitudes and densities.
