PHYSICSIn what ways do photons resemble other particles such as electrons? In what ways do they differ? Do photons have mass? Do they have electric...

High energy photons such as gamma rays have a wavelength
of about 10^-11 metres. They can be thought of as particles of this
size.

The classical electron radius is about 10^-15 metres.
So their size isn't comparable.

Photons have no charge,
electrons are charged. They have no mass but an electron is about 9 x 10^-31
kg.

Photons can't be accelerated they only ever travel at
the speed of light. Electrons can be accelerated (as in a cathode ray
tube).

Photons do have momentum but not in the usual
mechanical sense.
