Are these right? Wave length = xd/L

Wave length = yw/L

If these are right can someone please explain what the variable stand for because I am at a loss due to the fact that I have lost my notes

-thanks

I1(x) + I2(x) + 2*sqrt(I1(x)*I2(x))*cos(delta)

Where

I1(x) = Intensity due to 1st slit

I2(x) = Intensity due to 2nd slit

delta = 2*pi*d/lambda

Where

d = distance between slits

lambda = Wavelength

I1(x) and I2(x) are gaussians i.e in the form Ae^(-(x-b)^2/a^2)

where A, b and a are constants determined by source intensity, slit width etc.

I have no idea what the equations you mentioned mean.
