How long would it take a radio wave with a frequency of 4.5 x 10^5 Hz to travel from Mars to Earth if the distance between the two planets is approximately 8.00 x 10^7 km?


Rate This Answer

Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period is half a second. ChaCha on!
