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 4b. decreases by a factor of 2c. remains samed. increases by a factor of 2

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

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

Resistance of a metallic conductor depends on ______.Select an answerAits lengthBits area of cross sectionCtemperatureDAll the above

Which one of these statements is trueSelect one:a.As conductor length increases, conductance increases proportionallyb.As resistance increases, conductance increases proportionallyc.None of these statements are trued.As conductor area increases, conductance increases proportionallye.As conductor area decreases, conductance increases proportionally

Choose TRUE if the statement is correct, FALSE if otherwise. The shorter the wavelength between waves, the higher its frequency. EM is composed of frequencies that are characterizes by solar radiation. Frequency is the distance between one point of a wave to the same point in the next wave. The amount of energy in the EM wave decreases as wavelengths get smaller and tighter.    EM waves with low frequencies have high energies, so are able to cause the most damage.
