What determines which photon an atom can absorb or emit?
Generally if they are of the same wavelength, then the atom will absorb the photon at that wavelength.
All molecular motion ceases at 0 Kelvin why?
All molecular motion stops at absolute zero because absolute zero is the coldest possible temperature. And it is only able to achieve this temperature if the molecules/atom do not possess any thermal energy. And thermal energy is what causes vibrating motion of the molecules/atom. Thus at this temperature no molecules/atoms will vibrate due to the complete lack of energy.
When would water molceles stop moving?
Theoretically, the only way to completely stop the movement of any atom or molecule is to reduce its temperature to absolute zero.
What temperature is absolute zero in degrees K?
Kelvin (K) is actually the same scale as Celsius (C), but whereas Celsius is set such that zero Celsius is the freezing point of water, the Kelvin scale is set such that zero Kelvin is absolute zero, which is the temperature at which all kinetic. Absolute zero is zero degrees Kelvin, at which point there is no kinetic activity in a molecule or atom. There are presently no theoretical means of achieving absolute zero.
In what field is De Broglie wavelength being measured?
The De Broglie Wavelength is being measured in the electromagnetic fields. The De Broglie Wavelength theory is related to Bohr's Quantum Theory and is about the energy of atom particles.
What does the wavelength of electron if it moves with the speed of light?
-- First of all, since the electron has rest mass, it can never move at the speedof light.-- Following DeBroglie, the electron's wavelength is such that an integral numberof them fit around the length of the electron's orbit when it's bound to an atom.
Does absolute zero really exist?
no, absolute zero is only a myth. Temperature is the measurement of thermal energy caused by the movement of the atoms. at absolute zero, atom freezes and it would be impossible to measure its temperature.

Why is there no temperature lower than 0 K?
Because that is 'absolute zero' it is the temperate where atom get so cold they stop moving.
What would happen to an atom if it reached absolute zero?
There is nothing "magic" about absolute zero. It's unattainable in practice, but theoretically nothing in particular would "happen" if an atom did achieve that temperature. If you were hoping for an answer like "the electrons would stop moving and collapse into the nucleus", no, sorry, that's not going to happen.
What is the wavelength of gamma ray?
The wavelength of a gamma-ray is 10-11 metres

Absolute zero is zero degrees Kelvin, at which point there is no kinetic activity in a molecule or atom. There are presently no theoretical means of achieving absolute zero.
Is it possible to see an atom using visible light?
No, it is not possible because the size of an atom is smaller than the wavelength of light.
Can you able to achieve hypothetical temperature?
Scientist can achieve almost hypothetical absolute zero using laser cooling trapping atom motion. The lowest temperature achieve is now approximately 0.00015 K. For absolute 0 K without any digit, it would be a very challenging task that may never be achieve.
Why it is not possible to find the absolute mass of an atom?
It is the smallest particle
