Yes it does. Although the photon has zero rest mass, it does have energy. From the relativistic relationships among Energy, Mass, and 

In a vacuum, unlike a particle of matter that may vary its speed but cannot reach the speed of light, a photon travels at only one speed, which is exactly the speed of light. Does the photon have mass?

Solution for Part 1. Photon momentum is given by the equation: p= h λ p = h λ. Entering the given photon wavelength yields. \ (\displaystyle {p}=\frac {6.63\times10^ {-34}\text { J }\cdot\text { s}} {500\times10^ {-9}\text { m}}=1.33\times10^ {-27}\text { kg}\cdot\text { m/s}\\\)

The quantum of EM radiation we call a photon has properties analogous to those of particles we can see, such as grains of sand. A photon interacts as a unit in collisions or when absorbed, rather than as an extensive wave. An atom absorbs a photon of wavelength 500 nm and emits another photon of wavelength 700 nm. asked Jun 6, 2018 in Physics by rubby ( 51.8k points) photoelectric effect able to encode two bits of information on a single photon.

The actual energy-momentum relation is E 2 = m 2 c 4 + p 2 c 2 and photons have m = 0. As Dick says, you got the right answer through the (apparently) wrong method. Technically you can say that p=140eV/c since "eV/c" are units of momentum :) Feb 8, 2013

C) What is the momentum of the photon? 2. Relevant equations P=m*V Plancks Constant: (6 Momentum of a Photon. Unlike a particle of matter that is characterized by its rest mass \(m_0\), a photon is massless.

more. You're right, the momentum of each individual photon is tiny. But when you have many trillions of photons striking an object per second, then the net momentum transfer can be significant. Comment on Mark Zwald's post “You're right, the momentum of each individual phot”. ( …

o Before the electron loses angular momentum to photon emission, the energy of the electron-nucleus is angular and electrostatic potential energy. At the moment the electron releases from the orbital electron, the electrostatic potential energy component diminishes. Because the photon definitely has energy, it must have a four-momentum vector, but it must be defined differently from m U because the proper time, τ, along its worldline is zero. d τ = d t 1 − v 2 / c 2 The photon four-momentum vector is defined to be p = [ p t p x p y p z] = [ E / c E v x / c 2 E v y / c 2 E v z / c 2], 2013-02-08 Photon momentum is indeed small.

This is a figure of speech that physicists use to describe something about how a photon's particle-like properties are described by the language of special relativity. Lasers can be designed to emit pulses of light smaller than 30 microns wide in their direction of motion. Estimate the uncertainty in the momentum of a photon in such a pulse.

Einstein explained the momentum (p) of a photon with the given formula.
