It is possible to hear light.

My esteemed opponent has not answered the objection of the fact that photons are nearly if not completely massless. Consider the equation E= Mc^2. A photon at rest must have no mass because it has no energy - 0 = [M(3.0 * 10^8)^2] - solving for M in this equation yields 0. Since a photon in motion is a manifestation of energy, its energy must equal its mass. The energy of a photon is calculated by: E=hv where: h = planck constant (6.63x10^-34 J s) v = nu = frequency = c/(wavelength) c = speed of light = 300x10^6 m/s The most energetic wavelength that could affect the human ear is 25000 hertz. In our case: E = (6.63 * 10^-34) * [(3.0 * 10^8) / 15000] E = (6.63 * 10^-34) * 20000 E = 1.326 * 10^-29 1.326 * 10^-29 = M * [(3.0 * 10^8)^2] M = 1.326 * 10^-29 / [(3.0 * 10^8)^2] In other words, the mass of a photon is: 0.00000000000000000000000000001326 / 90,000,000,000,000,000 This number is so close to 0 that it is pointless to calculate it. With the mass of the photon being practically 0, the amplitude of the wave is also practically irrelevant. The amplitude of the wave would need to be so great that there is simply no way of producing it. Without any plausible way to produce such an amplitude, my opponent has proven absolutely nothing. As the instigator, the burden of proof is on him to show his proposition plausible. He has utterly failed in this regard. Some responses: >> "My opponent makes the observation that light of such a small frequency as to be with in our audible range would not be energetic enough to make contact with the eardrum." This is not what I said - what I said was that it "cannot vibrate the molecules in the eat" later qualified by "not be enough to cause a vibration strong enough to produce an audible noise." >> "Thus any wavelength and frequency of light can put energy into the ear. The only problem is if it is within our sound range. Which I have proven plausible." My opponent says any, and then requalifies it as any within our sound range... which is far from "any" considering we can only hear about a 20 Gh range of the IMMENSE light spectrum. So it is indeed FAR from "any" light wave. He has not in any way proven that his method is plausible at all. >> "My opponent also brings up the fact that if light in this range were to strike the ear and cause a vibration it would go unheard. If so we could jack up the wave's amplitude, thus amplifying the sound to an audible point with out changing the frequency." Again, if the sound goes through some sort of device, we are hearing a representation of the sound, and the vibrations on our ears are caused by sound waves, not photons. In fact, his method is FAR from plausible, as the energy of a photon is infinitesimal, and the mass is that energy value divided by 90 Quadrillion. The energy required to increase the amplitude of the light's wavelength to a level where it would produce enough energy to actually vibrate the eardrum is immense and even imPLAUSIBLE to create. *************************************** As noted above, my opponent has not shown that his proposition is even plausible. The burden of proof is on him to show a way in which this could be done. Bombarding the eardrum with photons of a certain wavelength with a certain amplitude may actually do the trick, but the burden is on him to show how to create enough amplitude to offset the .00000000000000000000000000001326 / 90,000,000,000,000,000 mass of a 25,000 hertz photon in order to make it actually interact with the eardrum. AFFIRMED.
