    1) rms of an ac is equal to the constant dc that produces same power or heating effect in a identical resistor. for a sinusoidal graph, rms voltage and rms current is (peakvoltage/under root of 2) and (peak current/under root 2) respectively

    the frequency of info wave is the freq of the modulated wave to change from one max to the other or from one min to the other. here it takes 100 microseconds to move from one max to other. so freq of info will be 1/100μ
