Of all electromagnetic waves, radio waves have the...?

Question

a - highest frequency and shortest wavelength
b - lowest frequency and longest wavelength
c - highest frequency and longest wavelength

Answer 1

The answer is b - lowest frequency and longest wavelength.

Answer 2

Do not be misled by psuedo-science. Light is definitely a wave; it consists of oscillating electric and magnetic fields as predicted by Maxwell's equations. These electric and magnetic fields can be sensed and measured; they are real. That is how your TV antenna picks up broadcast signals. Light is ALSO a particle. It is an example of wave-particle duality. When this was first discovered, it was actually proposed that the term "wavicle" should be used. Even what we think of as solid particles act like waves as well. An electron will exhibit wave properties such as refraction and interference. Everything is both a wave and a particle.

Radio waves are the lowest frequency and longest wavelength of all NAMED electromagnetic waves, but electromagnetic waves can exist at much lower frequencies than what we call "radio".

Answer 3

Of the 3 choices you present, only "a" has a chance of being correct. Since frequency is inversely proportional to wavelength, "c" can never be correct. The answer "b" cannot be correct because radio waves are high frequency... but of all electromagnetic waves, are radio waves the highest frequency electromagnetic waves? The answer is NO! Above radio waves are much higher electromagnetic waves. There are microwaves, soft and hard x-rays, infrared and ultra violet waves.

Answer 4

light, in spite of what you are taught, is a particle, not a wave... but it has a frequency of orbiting, and since it moves forward through space as it is orbiting, it traverses a HELICAL path.

a helix, seen from the front, appears like a circle, but from the side, a helix looks like a sine wave, and there are calculations that work as if light WERE a wave. however, these calculations can be done by treating light as a particle with probability functions when it encounters matter.

that is, if a window tint absorbs 60 % of light, each photon has a .6 probability of being captured as it passes through.

there is no LOWEST frequency of photons, some photons probably have "wavelengths" as big as the universe.
