Assuming the photon is reflected into the same medium it came from (so we can ignore refraction), its momentum differs only directionally, its magnitude stays the same. The directional component of its momentum vector is always pointing in the direction it's propagating.
Refraction is the means by which the magnitude component of the vector changes.
The change in momentum of photon is nh/lambda.
What else can I help you with?
What do you call a particle of light with zero mass which carries a quantum of energy?
I call it a 'photon'.By the way, the photon has zero rest mass, but when it travels at the speed of light ...which it always does ... it has some mass.
How is momentum conserved in pair production?
Basically, the two particles fly off in opposite directions.Basically, the two particles fly off in opposite directions.Basically, the two particles fly off in opposite directions.Basically, the two particles fly off in opposite directions.
What happens when a photon strikes an atom?
well thats a theory i believe that will work with space travel or FTL travel,the photon wil make the electrons go crazy,so crazy that the nucleus either dissolves or becomes negatively charged and just flies away with the electrons orbiting the photon,and make matter travel the speed of light,i like to call this particle a "photom"
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
If the photon has a frequency of 4 x 1015 Hz how did the energy of the electron change?
If the change in energy of electron is totally exhibited as a photon then the energy = h times frequency. h = 6.626 x 10 to -34 J s Simply multiply h and frequency you would get the energy in joule
How many reflected rays can there be for a single incident ray falling on a plane mirror?
Substitute "photon" for "ray" and it's one. One photon falling on a plane mirror will come back off of the reflective surface if that reflective surface does not absorb it. (In a perfect plane mirror, every photon that falls on the surface will be reflected.) A photon does not "create" a second photon in a reflection event.
How do you increase the momentum of a photon?
To increase the momentum of a photon, you can either increase its frequency or velocity. This can be achieved by changing the energy of the photon, as momentum is directly proportional to the energy of a photon.
What is the four momentum of a photon and how does it relate to its energy and momentum?
The four momentum of a photon includes its energy and momentum in a single mathematical expression. The energy of a photon is directly related to its frequency, while its momentum is related to its wavelength. The four momentum of a photon helps describe its motion and interactions in the context of special relativity.
What is the angular momentum of a photon?
The "intrinsic angular momentum" of particles is commonly called "spin". The spin of a photon is 1, in the units commonly used.
What factor among the following would lead to an increase in the momentum of a photon?
The factor that would lead to an increase in the momentum of a photon is an increase in its frequency.
Which is not the property of photon mass charge energy momentum?
A photon has zero electrical charge.
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.
What is the mass of moving photon?
A photon is a massless particle, so it does not have a rest mass. It only possesses energy and momentum, but in the context of special relativity, mass is not a property of a moving photon.
What is the momentum of moving photons?
momentum is equal to h/lambda or E/c. (By the way ... there's no such thing as a non-moving photon.)
Does a body with zero mass can transport momentum?
Technically speaking, something with zero mass would not be considered a "body" in the physical sense of the word. It is possible for mass-less particles, like photons to have a momentum. The debroglie wavelength of a photon is inversely related to its momentum. This is not momentum in the classical sense, as a car might have while it is driving, therefore it must be calculated differently. The momentum of the photon is given by : hf/c. h is the Planck constant, c is the speed of light and f is the frequency of the photon.
Can photons collide with each other?
Yes, photons can interact with each other through a process called photon-photon scattering, where they can exchange energy and momentum.
What is the mass of a photon in motion?
It's (double the photon's energy) divided by (the speed of light squared). The photon's energy depends on its frequency, and is (frequency) times (Planck's konstant).
