An infrared wave traveling through a vacuum has a frequency of 4.0 x 1024 Hz. What is the wave's wavelength?
* 7.5 x 107 m
7.5 x 10-7m
1.2 x 1024 m
1.2 x 10-14 m

70,000 + 6,000 + 800 + 30

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
