What is the speed of a photon with respect to another photon if a the two photons are going in the same direction and B they are going in opposite directions?

Related Videos Assertion : The relative velocity of two photons travelling in opposite directions is C. > Reason : The rest mass of a photon is zero . Assertion : The relative velocity of two photons travelling in opposite directions is C. Reason : The rest mass of a photon is zero .

Can photons collide each other?

Since light itself does not have electric charge, one photon cannot directly interact with another photon. Instead, they just pass right through each other without being affected. However, two photons heading towards each other can indeed collide indirectly.

Do photons move at the speed of light?

Through the vacuum of space, no matter what their energy is, they always travel at the speed of light. The highest-energy photon and the lowest-energy photon ever observed both travel at exactly the same speed. All massless particles travel at the speed of light, including the photon, gluon and gravitational…

When two photons approach each other their relative velocity is?

Originally Answered: If two photons approach each other, what is their relative velocity? The relative velocity of photons is zero. The speed of light (the exchange rate) between space and time, has to be set at 1.

What if we move at speed of light?

The person traveling at the speed of light would experience a slowing of time. For that person, time would move slower than for someone who is not moving. Also, their field of vision would change drastically. The world would appear through a tunnel-shaped window in front of the aircraft in which they are traveling.

Can two photons travel at the speed of light at once?

Special Relativity equations for two photons, no matter which direction they are traveling to each other, always has the speed of “both” photons moving at the speed of light, as measured in the reference frame of the measuring device. Yes, it’s very odd, counter intuitive]

Can a photon be used to measure time?

Thanks guys, Tapio and Giovanni, learned something about special relativity from you! As the photon is travelling the speed of light, any measurement of “time” “by the photon” is not possible. Time rate goes to zero when travelling at the speed of light.

What is the relationship between wavelength and energy of a photon?

The energy of a photon is inversely proportional to the wavelength of a photon. The Photon energy formula is given by, Where. E = photon energy, h = Planck’s constant (6.626×10−34 Js) c = speed of the light and. λ = wavelength of the light.

What is the distance between two points on a photon?

That is, the distance between any two points on a photon’s trajectory (in the vacuum) is zero. In general relativity, such paths are called ‘null geodesics’. Special Relativity, a theory published by Albert Einstein, back in 1906, plus or minus a year, is accepted by the widest scientific community as the last word on the speed of light.
