Assuming the time lapse indicated by the double arrow is 2s, what are the values of the wave frequencies f1 and f2 in the figure? (Hint: Use the definition of frequency).

f₁ = 1 Hz

f₂ = 0.75 Hz

Explanation:

The given time lapse between the two frequencies, t = 2 s

The frequency of a wave is the number of complete one cycles of the wave that pass through a given point in a given unit of time

The unit of frequency, 'f', is the Hertz, Hz

Therefore, frequency = Number of cycles/(Time)

The frequency of a wave, f = n/t

Where;

n = The number of completed cycles in a given time

The frequency of the first wave 1, f₁

The number of complete cycles by wave 1 in the 2 seconds, n = 2 cycles

The time, t = 2 seconds

The frequency of wave 1, f₁ = 2 cycles/(2 seconds) = 1 cycle/second = 1 Hz

The frequency of the second wave, wave 2, f₂

The number of complete cycles by wave 2 in the 2 seconds, n = 1 and half cycles = 1.5 cycles

The time, t = 2 seconds

The frequency of wave 2, f₂ = 1.5 cycles/(2 seconds) = 0.75 cycle/second = 0.75 Hz

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
