James clerk maxwell predicted a. the speed of light b. that light had a finite speed c. that light was an electromagnetic wave d. that light was both a wave and a particle

James Clerk Maxwell predicted that light was an electromagnetic wave. The answer is C. He had developed a theory that explained the relationship between electricity and magnetism and correctly predicted that visible light is caused by electromagnetic waves. (credit: G. J. Stodart)

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
