(a) Determine the attenuation constant, the phase constant, and the intrinsic impedance. (b) Find the location at which the amplitude of H is 0.01 (A/m). (c) Write the expressions for E(y, t) and H(y, t) at y

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
