Concentrated in short wavelengths: ultraviolet, visible, and shortwave infrared. Work: the product of the force applied to an object and the distance through which the object moves. 1st law of thermodynamics: energy cannot be created nor destroyed, but may be transformed from one form to another . * we assume there is a fixed amount of energy in the universe. Potential energy - energy stored by virtue of position. Nuclear fusion - combining nuclei to form larger nucleus. Emitted by all bodies with a temp > absolute zero (-273 c) Radiant energy travels in electromagnetic waves that vary in wavelength and. Radiant energy - energy from the sun. frequency. Measured in units of hertz (1 hz = 1 oscillation) Travels at the speed of light in a vacuum. * frequency - waves per second (sinusoidal curve) Longer wavelengths up to tens of miles, decreasing frequency.
