    1 / ✓ Permeability x permittivity = light speed equation ? 👇👇
    ϵ=8.854×10(-¹²)
    μ=4π×10(-⁷)
    c=1÷✓ϵμ=2.998x10⁸m/s

    VIDEO REQUEST: Can you discuss the inventions found because of the World Wars + And how are we using them today + how those inventions got evolved today? (Just For example, if the world war leads to the invention of calling only phones, then it got developed into what we’re using it-like a small computer-nowadays.)

    உண்மையில், ஒளியின் ஒரு வழிப் பயணத்தின் நேரத்தை அறிவியல் வளர்ந்துள்ள இந்த காலம் வரையிலுமே ஒருவரும் துல்லியமாக அளக்கவே இல்லை. ஒளி ஒரு சுற்றுப் பயணத்தை முடிக்க எடுத்த நேரத்தை மட்டுமே நாம் அளந்திருக்கிறோம். ஒளியின் வேகம் இரு வழிகளிலும் ஒரே வேகத்தில் இருக்கும் என்ற அனுமானத்தின் அடிப்படையில் அதன் வேகம் ஒரு நொடிக்கு 2,99,792 கிலோமீட்டர்கள் மற்றும் 458 மீட்டர்கள் என்று தீர்மானிக்கிறோம்.

    ஏனென்றால் ஒளியின் வேகத்தை அடிப்படையாக வைத்துதான் relativity theory விளக்கப்பட்டது 😮

      ​@@Aalanfu As per my knowledge and my pov :
      E = mc², here the 'c' denotes the speed of light in vaccum which is constant and the speed is faster in vaccum due to no particles in vaccum so no problem in the special relativity theory and,yes speed of light changes in different medium,becoz light is a transverse wave electro magnetic wave which has a particle photon that has no mass ,the photon particle colloid with the particles of the medium that reduces the speed and creates change in speed,also when we see light due to the changes in different medium a phenomenon refraction takes place.

      The equation E=mc^2 applies to particles with mass. For massless particles, like photons (particles of light), the equation is yextended to
      E=pc, where p is the momentum of the photon. This relationship shows that even though photons have no rest mass, they still carry energy proportional to their momentum, with the speed of light being the proportional constant.
