If the frequency of a wave is 2.0 cycles per second and its speed is 0.04 meter per second,what is the wavelength of the wave?

Answer 1
#(0.04 m/s)/(2.0 s^(-1))=0.02 m#
To solve this problem, start with the fact that the desired answer (wavelength) has units of meters (#m#). Therefore, you will want the wave speed (#004 m/s#) in the numerator of the expression in order to get #m# in the numerator of the answer.
The next challenge is to get #s# out of the denominator. You can do this by dividing by the frequency (#2.0 s^(-1)#), because diving by #s^(-1)# is equivalent to multiplying by #s#. In other words, a unit that lies in the denominator of the denominator is equivalent to being in the numerator.

Your answer should be in units of "m/cycle" if you included "cycles" as a unit. Write out the entire expression and make sure all the units cancel.

Answer 2

Wavelength is equal to speed times frequency, or 0.04 m/s / 2.0 cycles/s. This equals 0.02 meters.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
