What term best describes light?
Electromagnetic radiation.
What term best describes light waves?
Electromagnetic waves.
Which property describes an electromagnetic wave and not a mechanical wave?
An electromagnetic wave does not require a medium to travel through, whereas a mechanical wave does. This property is known as the ability of an electromagnetic wave to propagate through a vacuum.
Which describes the speed of electromagnetic waves?
Electromagnetic waves travel at the speed of light, which is around 299,792 kilometers per second in a vacuum. This speed is constant and does not change based on the frequency or wavelength of the waves.
What is the solution to the electromagnetic wave equation?
The solution to the electromagnetic wave equation is a wave function that describes the behavior of electromagnetic waves, such as light. This wave function includes both electric and magnetic fields that oscillate perpendicular to each other and to the direction of wave propagation.
