For the low-pass rc filter, calculate the phase and magnitude of the transfer function at frequencies of 20, 50, 100, 200, 500, 1000, and 1500 hz. tabulate the result and then sketch the magnitude and the phase of the response as function of the frequency (use log scale for frequency). use r=50 k, c=0.02 f

What is the frequency of a light wave with a wavelength of 620nm

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
