Are the variables "E" is E=hc/wavelength, and the Ek in the threshold energy equation the same?

They are different. "E" is the overall energy of the photon while "Ek" is the kinetic (movement) energy of that electron when it interacts with a photon.

The E in E=hc/wavelength is the energy per photon, while the Ek in the threshold energy equation is the kinetic energy that is released when the energy of the incoming light is greater than the threshold energy.

E(photon) = hv, whereas Ek or E(electron) = 1/2 mv^2
E(photon) = threshold energy + Ek
