Is threshold a constant value? Also is hvphoton= threshold +1/2MeV^2 or is hvphoton +theshold = Kinetic energy

You will normally be given the threshold value, but it is not a constant value. Also, it is hvphoton= threshold +1/2mv^2.

It is not a constant value and may come with units like kJ/mol, so you can change it's value by changing the units.

No, the threshold is not a constant value. The question should specify your threshold
