The photoelectric equation is given by:
hf = hf0 + 1/2mv2 where f is the frequency of the incident wave and f0 is the threshold frequency.
HERE, only the conservation of energy is taken into consideration and momentum conservation is neglected. Why is this approach justified? Suppose we take momentum conservation into consideration--how will the photoelectric equation be modified?
What qualitative changes will be introduced in the emerging electron?
