Let m represent the mass of an electron, and c represent the speed of light. In order

Fantastic news! We've Found the answer you've been seeking!

Question:

Let "m" represent the mass of an electron, and "c" represent the speed of light. In order to create an electron-positron pair, we must start with a photon whose energy is

at least mc ².

at least 4mc ².

at least 2mc ².

any value greater than zero.

Actually it is impossible to create such pairs from photons.
