Answer:
[tex]x=8.4x10^{7} cycles/min[/tex]
Step-by-step explanation:
To answer the question we have to use the rule of three.
If in a second the radio wave does [tex]1.4x10^{6}[/tex] cycles, how many cycles would do per minute, that is, in 60 seconds?
[tex]x=1.4x10^{6}\frac{cycles}{sec}\frac{60 sec}{1min}=84x10^{6} cycles/min \\x=8.4x10^{7} cycles/min[/tex]
Therefore, the frequency would be [tex]x=8.4x10^{7} cycles/min[/tex]
