Answer to Question #80087 in Physics for DEVENDRA SINGH

Question

2. b) A surface wave with frequency w = 3 × 10−5 rad s−1 is propagating at a metal-free
space boundary. The plasma frequency of metal is 9 × 1015 rad and er = 7. Estimate
k. If the amplitude of the wave is 105 Vm−1 at the surface, what will be its value at
the depth of 0.2 μm in the metal? Ignore the collision effect.
