How does the speed of a photon compare to the speed of an EM wave?
Wave length of gamma rays is 10 raised to the power of minus 12. It means that you have 10 raised to 12 waves in case of gamma rays/ meter. Wave length of radio wave is 10 raised to 3. So there is difference of '12' zeros between both of them. But the speed of electromagnetic wave is about 300,000,000 meters/ second. It means that photon travels about 300,000,000 meters/second. So the actual distance traveled by photon in case of radio wave is little more than 300,000,000 meters. So in case of gamma rays the distance traveled by photon is 1,000,000,000,000 *1000 = 1000,000,000,000,000 times that of radio wave per second.
What happens to an electromagnetic wave when the frequency is doubled?
When the frequency of an electromagnetic wave is doubled, its energy and wavelength remain the same but its photon energy increases. This higher frequency wave will have shorter oscillation periods and carry more energy per photon compared to the original wave.
What is a photon-?
A particle of light. Or, in general, of an electromagnetic wave.
What is the wave-number of a photon?
The wave number of a photon is the spatial frequency of the photon's electromagnetic wave. It is defined as the reciprocal of the wavelength of the photon, typically measured in units of inverse meters. As the wave number increases, the wavelength decreases, and vice versa.
What is the name for the unit used to measure the energy of an electromagnetic wave?
The unit used to measure the energy of an electromagnetic wave is called a photon.

How do the velocities of a sound wave and electromagnetic wave compare to each other?
In air at sea level, the speed of electromagnetic waves isroughly 882 thousand times the speed of sound.

Discrete bundle of electromagnetic energy?
A photon is a discrete bundle of electromagnetic energy, carrying a specific amount of energy and momentum. Photons do not have mass and travel at the speed of light in a vacuum. They exhibit both wave-like and particle-like properties.
What happens to an electromagnetic wave when frequency is doubled?
The speed halves.
What is photon characteristics?
Under the photon theory of light, a photon is a discrete bundle (or quantum) of electromagnetic (or light) energy. Photons are always in motion and, in a vacuum, have a constant speed of light to all observers, at the vacuum speed of light (more commonly just called the speed of light) of c = 2.998 x 108 m/s.
What As frequency increases in an electromagnetic waves its photon energy decreases?
As frequency increases in an electromagnetic wave, the photon energy increases, not decreases. This is because photon energy is directly proportional to the frequency of the electromagnetic wave, as described by Planck's equation E=hf, where E is energy, h is Planck's constant, and f is frequency.
What does the term photon refer to?
A photon is a fundamental particle of light that carries electromagnetic energy and behaves as both a particle and a wave. It has no mass and travels at the speed of light. Photons are the basic unit of all electromagnetic radiation, including visible light, radio waves, and X-rays.
Why does an electromagnetic wave in space never slow down?
In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.
