Homework Statement
In a certain reference frame, a particle with momentum of 4 MeV/c and a total energy of 5 MeV
(a) Determine the mass of the particle.
(b) What is the total energy of the particle in a reference frame in which its momentum is 4 MeV/c?
(c) What is the relative speed of the two...
I am trying to understand what you are saying. The wording to me is a little confusing. So you say that 2d+(1/2λ)=λ, 2λ... Since there are 19 fringes seen, then 2d+(1/2λ)=19λ, as 19 is the n. So 2d=18.5λ if the fringe is right on the edge? I see now, I realized I made a mistake as I did on an...
Well we are told at least 19, in that it could be at the edge, but less than 20, as in the 20th is not there so it being less than but not able to be equal to. So in what ways does the number of fringes per wavelength effect my answer? Because I was going off of what I saw in other posts in...
