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)

What is the energy of a photon emitted with a wavelength of 92.323 nm?
The energy is 2,5116.10-18 J or 13,429 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. To put this into perspective, a single photon of visible light has an energy of 1.8 to 3.1 eV, and a single photon of ultraviolet light has an energy of 3.1 to 124 eV. The energy of a 500 nm photon can be calculated by using the following equation: E = hc/ Where: E = energy of the photon (in eV) h = Planck's constant (6.626 * 10-34 Js) c = speed of light (2.998 * 108 m/s) = wavelength of photon (in meters) Therefore, the energy of a 500 nm photon is calculated as follows: Convert the wavelength from nanometers to meters: 500 nm = 0.0005 m Insert the values into the equation: E = (6.626 * 10-34 Js) * (2.998 * 108 m/s) / (0.0005 m) Calculate the energy: E = 3.1 eVTherefore, the energy of a 500 nm photon is 3.1 eV.

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.
What band of freqency does the Photon work?
Photons can have any frequency: 0 Hz (0 eV) to infinite Hz (infinite eV).
