What is the contribution of Maxwell in electromagnetic wave theory?
About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves.
Why did Maxwell think light was an electromagnetic wave?
At the time, there was a lot of talk that light was somehow linked to Electricity and Magnetism, so as Maxwell showed, mathematically, that these as yet hypothetical waves were moving at the speed of light, he concluded that light was an electromagnetic wave: the coincidence, he thought, was simply too great.
What is Maxwell electromagnetic theory?
Maxwell’s complete and symmetric theory showed that electric and magnetic forces are not separate, but different manifestations of the same thing—the electromagnetic force. In fact, Maxwell concluded that light is an electromagnetic wave having such wavelengths that it can be detected by the eye.
What is the shortest electromagnetic wave?
Gamma rays
What color has the greatest frequency?
violet
Which color has the most energy?
Violet has the most energy in the visible light spectrum. This is because it has the shortest wavelength (approximately 400nm) and highest frequency meaning more waves and more energy is being transferred from point A to point B in a very short amount of time.
What color has the highest energy?
What color of visible light is lowest in energy what color is highest?
Red is the lowest energy visible light and violet is the highest. A solid object has color depending on the light it reflects.
Why does blue absorb red light?
Pure pigments absorb a single frequency or color of light. The color of light absorbed by a pigment is merely the complementary color of that pigment. Thus, pure blue pigments absorb yellow light (which can be thought of as a combination of red and green light).
