i hope this helps-
The basic relationship between frequency of an electromagnetic wave and wavelength of the wave is

where

is the speed of light.
Manipulating the equation, we can rewrite it as

The frequency of the wave in our problem is

so if we use the previous formula, we find the correspondant wavelength:
decreased 5 times
Explanation: if the force increases 5 times between them would decrease 5 times
Answer:
E= 71dB
