Thank you ehild

I am aware there are two coefficients of each, actually there are 4: Rs,rs,Rp,rp,Ts,ts,Tp,tp. And yeah, I'm not sure of how to use the coefficients... this is why I ask it here. I've already seen these links before I asked and they refer to lower-case-coefficients which I think are...

Homework Statement Hello! This is really a simple question about how to use reflection and transmittance coefficients. I have a light ray of intensity I0 comming (S-polarized) to a glass surface at a certain angle, like in the picture: I want to find the intensity of the reflected...

The 180 degrees shift at reflection would be expressed by a minus sign in the reflection coefficient. But what about the shift lag from the extra path? I am not sure I understand

Homework Statement I hope this question is better suited to this forum... (See picture) We have 3 areas in which a wave can move. The wave Y1 starts at area 1 and goes towards Border 1, some part of it is passed to Area 2. That part goes towards Border 2, and some part of it is reflected...

Homework Statement (See picture) We have 3 areas in which a wave can move. The wave Y1 starts at area 1 and goes towards Border 1, some part of it is passed to Area 2. That part goes towards Border 2, and some part of it is reflected back into Area 2. That part moves towards Border 1...

My understanding is that the phase is extremely important, since the next step would be to find the intensity by integration of z|b'(t)|^2 (which is the instantaneous intensity) over [0,T] (because the wave exists in [-T,T] and there is no negative time], and T is not neccesarily the period, its...

I'm really not sure I'm getting where you're going with this. When w=w0, B(w)=V0. So its symmetric around w0. I do expect Bw to be different for different values of w, but that is true whether b(t) is even or odd or neither. Does it tell me anything about the symmetric properties of b(t)?

Thank you rude man

I don't really know how to sketch it since it has an imaginary part... Do I take only the real part? I which case it is not odd, but even. As to B(w), it is not even and not odd, I think. So can it tell me something about the form of B(t) just by examining it?

Nope :(

Hello, I'm trying to figure out a solution of a question I saw, I'll ask it here in this forum because perhaps this is where it belongs. Let's say I have a Pulse wave that I am given it's frequency spectrum: B(w) = V_0\frac{Sin[(w-w_0)T]}{(w-w_0)T} Where V0, T, w0 are constants. So I do...

I'm trying to figure out a solution of a question I saw... So this is where the question comes from. Let's say I have a Pulse wave that I am given it's frequency spectrum: B(w) = V_0\frac{Sin[(w-w_0)T]}{(w-w_0)T} Where V0, T, w0 are constants. So I do an inverse Fourier transform to get the...

So in our case (Heaviside(t+T)−Heaviside(t−T)) is an even function, and the Re{exp(-iwt)} = cos(-wt) = cos(wt) is an even function, so the function of their multiplication is also even?

Homework Statement Hello! I have a basic question about how to mathematically treat waves. I've seen many times a guess of a wave of the form Ae^{iwt} My question is, how do I actually know what is the amplitude in t=t0? Do I take the real value only? The imaginary value only? For...
