The depth of penetration of a wave in a lossy dielectric increases with increasingSelect one:a. Conductivityb. Permeabilityc. Wavelengthd. Permittivity

For an electromagnetic wave incident on a conducting medium, the depth of penetration Select one:a. is inversely proportional to the attenuation constantb. has logarithmic relationship with the attenuation constantc. is independent of the attenuation constantd. is directly proportional to the attenuation constant

If the frequency of a plane electromagnetic wave increases four times, the depth of penetration, when is incident normally on a good conductor will Select one:a. decreases by a factor of 2b. increases by a factor of 2c. decreases by a factor of 4d. remains same

he refractive index and permeability of a medium are 1.51.5 and 5×10−7 H m−15×10-7 H m-1 respectively. The relative permittivity of the medium is nearly

he electromagnetic wave travels in a medium at a speed of 2.0 × 108m/s. The relative permeability of the medium is 1.0. The relative permittivity of the medium will be:
