Though it may be imprecise, when people refer to the size of a photon, they are talking about the wavelength associated with it. Seen in this way, the photons detected by the human eye are 4000 to 7000 angstroms (an angstrom is 1x10-10 meters). Numbers and measurements on such a scale are hard to imagine, but by comparison, a helium atom is about 1 angstrom, and the largest atoms are about 7. UV photons, X-rays, and gamma rays are smaller. Wavelengths of radio frequency photons can be very big, ranging from a millimeter to many kilometers.

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 are 4 causes of scatter radiation?

Compton scatter: Interaction between an incoming X-ray photon and an outer-shell electron results in the photon changing direction. Photoelectric effect: Absorption of X-ray photon by inner-shell electron leading to emission of a secondary photon. Pair production: High-energy X-ray photon interacts with atomic nucleus, creating an electron-positron pair. Rayleigh scatter: Low-energy X-ray photon interacts with an atom without ionization, resulting in a scattered photon with the same energy.


How to Put these photons in order of increasing energy?

To arrange photons in order of increasing energy, you can use the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. Photons with higher frequency will have higher energy. So, simply compare the frequencies of the photons to determine their energy order.

Can the energy of a photon be zero?

No. But if the photon has a very large wavelength (and a very small frequency) its energy can be very close to zero.

Which is more energetic a red photon or a blue photon?

The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.


What is the opposite of a photon?

The opposite of a photon is an antiphoton.


How do you calculate photon flux given v?

Photon flux can be calculated using the formula: photon flux = v * E, where v is the frequency of the photons and E is the energy of each photon. By multiplying the frequency of the photons by the energy of each photon, you can determine the photon flux.

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.
