What is the speed of a light wave?
299 792 458 m / s, and the speed is the same for a photon (this speed is in a vcuum)
How does the speed of a photon compare with the speed of an electromagnetic wave?
Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.
What is the speed limit in the fast lane?
The speed limit in the fast lane is the same as the speed limit for the road or highway you are driving on.
What is the speed of a photon of red light if its frequency is 4.3 x 1014 Hz?
The speed of light in a vacuum is approximately 3.00 x 10^8 m/s. You can calculate the speed of the photon using the formula speed = frequency x wavelength, where wavelength = speed/frequency. Given the frequency of 4.3 x 10^14 Hz, you can calculate the speed of the photon.
Is that true that the more energy of a photon the bigger the mass it possesses?
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
How fast is electromagnetic energy?
It is the same as the speed of light.
If the speed of a car and truck is 80 at the same time who will be moving fast?
80 is fast.
What is the same for all photon traveling through a vacuum?
Speed. All photons traveling through a vacuum travel at the speed of light.
What would be the speed of the following particles if they had the same wavelength as a photon of blue light?
It's really difficult to select one from the list of choices that you submitted along with your question. We can only surmise that the speed of a 'following' particle might be the same or less than that of a leading particle.
Do all wavelengths travel at same speed in a vacumm and carry the same energy per photon?
Yes, all wavelengths of electromagnetic radiation, including visible light, radio waves, and X-rays, travel at the same speed in a vacuum, which is the speed of light (~3.00 x 10^8 m/s). However, different wavelengths carry different amounts of energy per photon, with shorter wavelengths (like gamma rays) carrying more energy per photon than longer wavelengths (like radio waves).
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 will happen if a photon is bouncing in between two mirrors and the apparatus is moving gradually in straight line approaching the speed of light.?
A person moving in the same frame as the moving mirrors would not be able to observe any change in the time it took the photon to travel between the two mirrors. It would not matter if the direction of travel was parallel or perpindicular to the motion of the photon, and this null effect would continue even if the observer was travelling at 99.9999% of the speed of light.
