The electron field portion of an electromagnetic wave is given by (all variables in SI units) E = 10^{-4}\sin(6\times10^{5}t -0.01\x). The frequency (f) and the speed (ν) of electromagnetic wave are

Correct Answer is : f = 300 / π kHz and ν = 6.0×107 m / s

f = 30 / π kHz and ν =1.5×10^7 m / s

f = 90 / π kHz and ν = 6.0×10^7 m / s

f = 300 / π kHz and ν = 6.0×10^7 m / s

f = 600 / π kHz and ν = 7.5×10^7 m / s

f = 900 / π kHz and ν = 8.0×10^7 m / s

The electron field portion of an electromagnetic wave is given by (all variables in SI units) E=10−4‌sin(6×105t−0.01x). The frequency (f) and the speed (ν) of electromagnetic wave are

f = 30 / π kHz and ν =1.5×107 m / s
f = 90 / π kHz and ν = 6.0×107 m / s
f = 300 / π kHz and ν = 6.0×107 m / s
f = 600 / π kHz and ν = 7.5×107 m / s
f = 900 / π kHz and ν = 8.0×107 m / s
