    What's the initial acceleration of a 'photon'?
    And I know photon has no rest mass, but what is the mass of the photon when it is in motion

    There is no acceleration. A photon is created moving at c. There's no time in it's existence when it's not moving at c. And it has no mass in motion.


    Its the way nature is!
    If you dont like it, go somewhere else....
    To another universe, where the rules are simpler
    Philosophically more pleasing, more psychologically easy
    Prof Richard Feynman (1979) .....

    Then during the emission of photon, How is it really possible to accelerate from 0 to 'C' velocity in absolute zero time period.
    And I have some scientific ideas and inventions, so where can I actually project it.

    There is no acceleration involved. When the photon comes into existence, it already moves at c; it does not start off at zero velocity.

    No. As already said, the photon is created travelling at c. There is no acceleration.

    You can also Calculate the Energy of a Photon of Electromagnetic Radiation for better understanding on how to calculate photon energy.
    Yes, the energy (and momentum) of a photon is related to its frequency.

    No, this is wrong, plain and simple. Photons do not accelerate, as has been explained to you several times now.
    Why do you even ask these questions if you ignore the answers provided ?

    To be fair (and I didn't notice this immediately) javedansari is not the one who asked the original question. But still, repeating false information after the question has been answered...
