Kinetic Energy and Speed of Light Variables

Postby Shirley Liu 2I » Sat Oct 20, 2018 10:37 pm

Is the variable "v" in the kinetic energy of an ejected electron equation (Ek=1/2 *Me*v^2) and in the speed of light equation (c=λν) the same? Are they both frequency?? I've been having trouble using both those equations to solve for specific values in the end

In the kinetic energy equation, v = velocity. It's kinetic so you know it's going to be velocity instead of anything else.

No, they are not the same.

In the speed of light equation (), the is frequency (in s-1 or Hz)

In the kinetic energy equation, , the is velocity (in m.s-1)
