Surface plot function with two variable

Hello, I am trying to reproduce the graph of the surface as shown in the image but I get only 'oscillation on one axis while the other remains constant. Does anyone have any advice?

Here my code

f= 0.5;
c = 3*10^8;
lambda = c/f
phi = 0
K = 2*pi/lambda
omega = 2*pi*f
E_0=1;
t = linspace(0,5,1000);
x =linspace(0,5,1000)';
E  = E_0.*sin(K*x-omega*t);
E = rot90(E);
[X,Y] = meshgrid(1:length(E),1:length(E));

surf(X,Y,E,'EdgeColor','interp')
xlabel('X axis')
ylabel('time axis')

Your x and t spans are not convenient. Try this

f       = 0.5;
tau     = 1/f;
c       = 3*10^8;
lambda  = c/f;
phi     = 0;
K       = 2*pi/lambda;
omega   = 2*pi*f;
E_0     = 1;

t       = linspace(0,tau*3,1000);
x       = linspace(0,lambda*3,1000);


[T,X]   = meshgrid(t,x);

E       = E_0*sin(K*X-omega*T);

surf(T,X,E,'EdgeColor','interp')
xlabel('Time axis')
ylabel('x axis')
