Homework Statement
The input signal of a first-order lowpass filter with a transfer function given by eqn 1 below and a half power frequency of 200 Hz is eqn 2 below. Find an expression for V_outHomework Equations
eqn1:
H(f) = 1/(1+j*(f/f_B) where f is the frequency and f_B is the half-power...
So, if the mirrors were 5cm apart would the equation d*sin(theta) = m(lambda) still work for the new fringes created? With d now being 5cm?
ie, would it would turn into something similar to a double slit experiment, just with light sources quite far apart and distance between the fringes...
I heard that if you put a laser through a diffraction grating, and then reflect the first order fringes back to the middle point you will create a second diffraction pattern within the bright spot you are creating. I have been asked to try to test this and would like to know whether or not it is...
