Explanation:
Light waves are electromagnetic waves. Electromagnetic waves are waves which means that they are disturbances in a particular physical medium and result in oscillations, but they differ from all other waves because they consist of 2 waves oscillating perpendicular to each other.One of these waves is an oscillating magnetic field and the other is electric.
Electromagnetic waves are characterized with their wavelength (lambda).
No all electromagnetic waves are visible to humans. The visible spectrum is the light that we can see with our eyes is only a small fraction from the whole spectrum.
A mass extinction is when a certain group of animals or species suddenly die in large quantities with little to no hope of having a large birthrate to rebalance the losses.
This would have large effects on other parts of the food chain, and would lead to many species overpopulating and then drastically dying off
Hope this help
