You know light and sound are the samething right? Not trying to start an arguemnet right now! But nothing travels faster then sound!
1-32 COMPARISON OF LIGHT WAVES WITH SOUND WAVES
There are two main differences between sound waves and light waves. The first difference is in velocity. Sound waves travel through air at the speed of approximately 1,100 feet per second; light waves travel through air and empty space at a speed of approximately 186,000 miles per second. The second difference is that sound is composed of longitudinal waves (alternate compressions and expansions of matter) and light is composed of transverse waves in an electromagnetic field.
Longitudinal sound waves need a medium to travel through, whereas transverse light waves do not.
Observations in nature, such as the time lag between thunder and lightning, show us that light waves travel faster than sound waves.
Sound Waves vs. Light Waves
You see a flash of lightning across the night sky. Five seconds later, your hear the rumble of thunder. If lightning and thunder come from the same source, then why don't they occur at the same time? Actually, they do occur at the same time. The time difference that you sense is due to the way sound and light travel. Light travels extremely fast (300,000,000 m/s). In fact, it is faster than anything else. Sound travels at a measly 343 m/s through air. Therefore we can see light in an instant, but it takes a while to hear thunder. Sound has another disadvantage because it tends to bounce off molecules in the air. This makes the sound travel in all different directions. The further away the source of the sound is, the more the sound gets distorted. Therefore, when you hear rumbling thunder, the lightning bolt was far away. When you hear a crack or boom of thunder, the lightning bolt is close to you (
Frequency is used to distinguish one color of light from another, as well as one sound from another. For example, red light is different from blue light because red light has a lower frequency.
One of the biggest differences between infrared light and visible light is their wavelengths; visible light goes from about 400 to 700 nanometers, but infrared light has a longer wavelength than visible. In fact, as you get redder and redder (or infra-redder, as the case may be), your wavelength continues to increase substantially.
Common experience tells us that the behavior of waves is much different than the behavior of particles. Wave phenomema has many common examples, but all waves share some common features. Waves have a frequency, a wavelength, a wave velocity, and an amplitude.
For Light (electromagnetic waves) travelling in a vacuum, this speed of propagation is mighty quick: 2.99792 x 108 m/s.
Newton and Einstein both thought that light, although a wave, can also have some properties of a particle. In fact, they were right. Light actually is a stream of particles called photons. The amplitude of the light can be related to the number of photons in a given volume, and the energy of each photon is related to the frequency of the light
Several interesting observations were readily apparent. Lock-on generally occurred very rapidly… within a quarter of a second in most cases. If lock-on did not occur at a specific frequency in the first second, it didn’t at all. When the brain did lock on, the amplitude of the brain waves increased to nearly double their normal size. This is typical for naturally (non-ELF) produced alpha patterns. The brain locked on to higher frequencies (9-10 Hertz) more readily, and maintained the lock-on for the entire duration of the transmission. As the frequency was lowered (below 8.6 Hertz), lock-on for most subjects occurred in bursts, rather than being continuous. For example, there might be immediate lock-on for two seconds; then the brain would “fight” the ELF frequency for a quarter of a second, and then lock-on again for another few seconds, etc.. I use the word “fight” because it looked like the brain was fighting the ELF to maintain its own frequency. The “fight” was characterized by low amplitude beta frequencies in the 15-20 Hertz range. These may, of course, have simply been analytical type thoughts, but they were not observed when the frequency was in the 9-10 Hertz range. This “fight” became more frequent as the frequency was lowered, until no lock-on was observed at all.
None of the subjects were able to consciously detect the presence of the ELF field. One female subject was able to detect whenever the field started or ended, but could not accurately say when if it was on or off at any given time. In other words, she was able to detect the change in the magnetic field, but not the presence or absence of the magnetic field itself. She thought she felt it because it aggravated her sinuses. When lock-on occurred, the brain waves lagged behind the transmitted ELF. This appeared to have been the “reaction time” of the brain to the ELF waves (approximately 60-80 milliseconds). More accurate experimentation is needed to explore this relationship.
Subjects verbatim reports were quite revealing. (Keep in mind that none of the subjects actually said they felt the ELFs.) The most common verbatim reports occurred between 8.6 and 9.6 Hertz. Common statements were subtle “tingling” sensations in the fingers, arms, legs, teeth, and roof of the mouth. Two subjects reported a “metallic” feeling in their mouth. One subject reported a “tightness” in the chest and another subject reported a “tightness” in the stomach. Several subjects also reported sensations when the ELF frequency was between 6 and 7 Hertz. The verbatim responses in this range were “ringing” in the ears, “flushed” face, “fatigued”, “tightening” in the chest and “increasing” pulse.
Conclusion light is sound!

While it's easy to mock someone for not understanding the difference, just think that there was also a point in your education where you did not understand it either.
Or quick and dirty: Light is radiation, Sound is vibration.
Also: "Not sure if trolling, or just doesn't get it"

I've already proven my point time and time again. If light has frequency light is sound.
