An aurora is a natural light show caused by charged particles from solar winds that flow through the magnetosphere and are then guided by Earth's magnetic field into the atmosphere. Energy is transformed into visible light as the charged particles collide with the atmosphere. The color of the aurora is determined by two primary atmospheric gases. What are the two primary gases and the corresponding visible light wavelength produced?
Oxygen and nitrogen atoms collide producing visible light at 750 nm and 400 nm respectively.
