p=momentum
m=mass
v=speed (in this case, speed of light)
therefore,
v=c
so start off with:
p=mv
substituting the speed of light you get:
p=mc
to find "m," use E=mc^2
isolate "m" and substitute it into the momentum equation
you get:
p=(E/c^2)c
p=E/c
easy.
now you'll need to turn that 140eV energy value into joules. conversion factor is (1.6*10^-19)
p=E/c
p=(2.24*10^-17)/(3.00*10^8)
p=7.4666666666*10^26
and there's your momentum. (you'll need to add units)

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 factor that would lead to an increase in the momentum of a photon is an increase in its frequency.
What is the energy of a single photon at a wavelength of 5nm in eV?
The energy of a photon is given by the equation E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength. Plugging in the values, the energy of a single photon at a wavelength of 5nm is approximately 2.48 eV.
What is the energy of a 500 nm photon?
The energy of a 500 nm photon is 3.1 eV (electron volts). This is a unit of measure used to represent the energy of a single photon.

If a photon is reflected from the mirror then the change in momentum of photon is?
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.
