Answer:0.2Hz
Explanation:
Frequency is defined as the number of cycles completed by a wave in one seconds. Frequency is therefore measured in cycles/second or Hertz(Hz).
Period (T) is the time taken to complete an oscillation. The relationship between both is that frequency (F) is the reciprocal of the period. Mathematically, F = 1/T
From the question, Period (T) is 5seconds
Frequency = 1/5
F = 0.2Hz
