Answer:
Frequency
Explanation:
Photons are the packet of energy. They are massless and chargeless particles. They travel in the vacuum with the speed of light. The energy of photon is given by :
[tex]E=h\nu[/tex]
Where
h = Planck's constant
[tex]\nu[/tex] = frequency of photon
Or [tex]E=\dfrac{hc}{\lambda}[/tex]
c = speed of light
[tex]\lambda[/tex] = wavelength of photon
From the above equation, it is clear that the energy of photon is directly proportional to its frequency.
