Anya recorded the temperatures of four different smooth materials after they were placed under a heat lamp for thirty minutes. A 2-column table with 4 rows. The first column labeled Material has entries W, X, Y, Z. The second column labeled Temperature (degrees Fahrenheit) has entries 87, 99, 75, 105. Which conclusion is best supported by the information in the chart? Material W is less absorbent than material Z. Material Y is the least reflective. Material X is more reflective than material W. Material Z is the least absorbent.

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
