Answer:
Line the numbers from smallest to largest the subtract the smallest from the largest numbers.
Explanation:
Answer:
A, 0.050 Hz
Explanation:
1) Frequency = speed divided by wavelength
time is 2* 60 = 120 seconds
distance = 6 wave lengths
speed = distance divided by time
speed = 6 wave lengths divided by 120
Hope this helps!
-- The unit of frequency is "per second" (Hz), which is [reciprocal time].
-- The unit of period is "second", which is [time].
Do you see where this is going ?
'Frequency' and 'period' are reciprocals of each other.
For any wave ...
Period = (1) / (frequency) .
Frequency = (1) / (period) .
