The rate of flow of electric CHARGE past any point is described in the unit of electric CURRENT ... the Ampere.
Answer: Option D and E
Explanation: Across the electromagnet spectrum, the frequency increases but the wavelength reduces.
This implies that radio waves have the longest wavelength but the smallest frequency, while gamma rays have the shortest wavelength but the highest frequency.
This implies that there is an inverse relationship between wavelength and frequency.
Of all the technologies listed above, wireless internet has the highest frequency hence making it have the shortest wavelength.
Also by comparing values from the data given to us above, it is possible for some wireless internet device to operate within the same frequency range of the microwave.
