In simple terms, light is one of natures freaky exceptions, and is considered to be both a wave and a particle. Electrons behave like particles and we can describe their exact paths. The range of visible light ends around 400 nanometers. This would be the correct answer if the question asked for a form of moving energy.However, the question asks for a form of energy, so we must keep looking. b.

The items inside can exchange energy with each other, which is why the drinks get cold and the ice melts a little, but they exchange very little energy (heat) with . The blades push air outward, creating a flow of air. The most common use of electricity is to provide artificial lighting. 1 Proceedings of the Royal Society B. Vol 281, published online July 4, 2014. doi: 10.1098/rspb.2013.2995. This means that the mass of an object will remain the same, regardless of what happens to it. Einstein then proposed that light is actually made up of tiny packets of energy thattravel or propagate in a wave-like manner. The total amount of energy in the universe remains constant. Her primary area of interest being human memory and learning, she is also interested in the neuroscience of cognitive processes. Red light has a shorter wavelength than violet light.
