Can something with higher Frequency than the frequency of light exist and if so can it surpass the light.

Question

I'm just a student and i wonder if that is possible.

Can we make something's frequency higher than the frquency of light?

that way can we make an proton or kind of message travel to the future ?

Answer 1

Hi Kaan,

Light is an electromagnetic wave (first described by Maxwell's unification of the laws of electricity and magnetism) or a particle (a photon, as described by Einstein's contribution to early Quantum theory through the Photoelectric Effect)

As a wave, light has the following speed (c) which is related to its frequency (f) and wavelength (λ)

c = f λ

Frequency and speed are not the same thing. Light can take on different frequency values, a small portion of which we as humans are capable of seeing with our own eyes as different colors. Regardless of frequency, all different "colors" of light still travel at the same speed, c, in a vacuum. Notice that by our above equation, this must mean that as frequency increases, wavelength decreases.

I think your question was instead supposed to be about the speed of light being faster than c.

According to modern physics (namely, Einstein's theory of Relativity), it is impossible for any particle or object (regardless of it being massive or mass-less) to reach speeds faster than the speed of light. I won't go into it but in the future you may choose to study the Special Theory of Relativity and see that the math disallows any massive particle to reach the speed of light. This is a core and foundational law in the theory of Relativity as a whole (Special and General theories), which has produced predictions that have been continuously verified over the past century. In fact the global positioning system (GPS) we use today would not be what it is without Einstein's theory of relativity. Relativity is not "just a theory" as people might use the word "theory" in an everyday sense. If a particle were discovered to be travelling faster than the speed of light, this would go against nearly everything humans have understood over the past 100+ years and be one of the craziest, if not the craziest discoveries of all time.

However, if you are curious about an interesting "paradox" involving quantum mechanics and the theory of relativity (specifically involving a supposed "violation" of the speed of light limit), you can read about the Einstein-Podolsky-Rosen Paradox (EPR paradox).
