For silver the conductivity a-3m s/m, what frequency will the depth of penetration be 1 mm? relative permeability of silver is 0. example: find the depth of penetration of a plane wave in copper at a power frequency of 10 60 hz and at a microwave frequency of 10 hz. given a -5.8x107 mho/m and hr-6

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.
