hey thanks for the response and input, but I'm afraid I don't really understand your advice. I have not studied Fourier transforms as such, and have only a vague idea about their purpose specifically in the context of diffraction in 2nd year physics. the only advice I have been given in...

In the following I am always talking about fraunhoffer diffraction suppose you have two slits in a doulbe slit diffraction experiment which are both exposed to the same plane wave (say the same laser) as the original source of radiation. Usually, we expect that both slits will act as EQUAL...

hey quick question about Fraunhoffer diffraction: RESTULT 1 for a rectanguar apperture, we have the following equation for irradiance I: I = I(0)(sin(B)/B)^2(sin(A)/A)^2 = I(0)[sinc(B)]^2[sinc(A)]^2 where, B = bu/2; A =...

hey, I was just wondering if someone could give me an explanation about the following: 1. why, physically, does light travel at different speeds in different medium 2. why is the speed at which it travels through different media dependent of frequency, as is the case with dispersion...

so when you say that the frequency of light is the greater player, is this the case: that a beam of light of definite frequency hits a prism, which, due to the inherent properties of that prism in conjunction with the specific frequency in question culminates in this case in a refractive...

Hi I'm trying to sort this concept out in my head and have reached a stumbling block! 1. ok so light travels through medium a and transmits through medium b and refracts. The angle or refraction is given by snell's law, and quantified by the refractive index of materials a and b. 2. But I...
