The period of a mechanical wave is 12 seconds. what is the frequency of the wave?

12 waves/second
4.0 waves/second
0.083 waves/second
depends on the speed of the wave

Data:
T (period) = 12 s
f (frequency) = ? (waves/second)

Formula:


Solving:

The radiation of the fire causes the saucepan to heat up. the conduction of the saucepan then to distribute the heat over the saucepan and to give heat to the water. the convection of the water distributing the heat within the water, till all the water is boiling

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth
