Speed of light and Energy of electromagnetic radiation?
If something has more energy, shouldn't it go faster? So does gamma rays go faster than visible light? I thought visible light's speed is the barrier beyond which nothing can go faster. So how is it that gamma rays, having more energy than visible light, has the same speed as visible light?

Do not get confused. Not all energy is transformed into velocity. Generally all electromagnetic waves or radiation have the same speed. There is also another equation though the plank’s E=h * f. where h is the plank’s constant and f the frequency of the wave…..now different frequency results to different wavelengths.....does it work out in your mind now?

No, more energy does not have to mean more speed.
A truck going the same speed as a car will have more kinetic energy because it is heavier, but it will not be going faster. The gamma ray is the truck.
By Maxwell's equations, EM waves can only travel at one speed, c.
A gamma ray has a shorter wavelength than visible light. You can try to think of a string: the more taut it is, the more energy it has, the faster it will vibrate (in cycles per second) producing a higher note - but the wave along the string will not travel faster.
So, long wave television signals, then radio waves, then visible, then X-rays, then Gamma, then cosmic radiation, all travel at the same speed.

More enegry does not mean its going faster. And it's all light, gamma, ultraviolet, radio, visible, infrared, x-ray. Electromagnetic radiation.

hi--sorry to be blunt, yet your notes are in all probability incorrect. Gamma rays and UV rays have greater potential than seen gentle, yet they commute on the comparable speed. All 3 (gamma, UV, seen) are electromagnetic radiation. the only exception to it rather is that if the sunshine is vacationing by something referred to as a "dispersive medium" which incorporate glass or water, which slows down distinctive frequencies by distinctive quantities.

OK - imagine two waves on the ocean. One is really big, the other is normal sized. Which one has more energy? Answer: the big wave.
Which one goes faster? Answer: they both go the same speed.

not so. gamma rays have more mass than photons. Hence the equation E=MC2. the only particals that are believed to travel F.T.L.
are called tachions, Which have virtually no mass at all.
