Slit Spacing

%% Slit Spacing
% Determines the distance between two slits and the distance between the
% central and mth bright fringe after the screen is moved

% Inputs and Variables
m = input('What order\n');
lambda = input('Wavelength\n');
x = input('x = \n');
y = input('y = \n');
move = input('Distance screen moved\n');

% Outputs and Equations
d = m*lambda*x/y;
xprime = x+move;
yprime = m*lambda*xprime/d;
fprintf('The distance between the slits: %.3e m\nThe new y distance: %.3e m',d,yprime)
