Answer:
The value is [tex]\lambda = 6.0*10^{6} \ m [/tex]
Explanation:
From the question we are told that
The frequency is [tex]f = 50 \ Hz[/tex]
The maximum electric strength is [tex]E = 13.0 \ kV /m = 13*10^{3}\ V/m[/tex]
Generally wavelength is mathematically represented as
[tex]\lambda = \frac{c}{f }[/tex]
Here c is the speed of light with value [tex]c = 3.0*10^{8} \ m/s[/tex]
=> [tex]\lambda = \frac{3.0*10^{8} }{50}[/tex]
=> [tex]\lambda = 6.0*10^{6} \ m [/tex]
