The Magnetic field in plane electromagnetic wave is given by `B_(y)=4xx10^(-6)sin (0.2xx10^(4)x+0.6xx10^(12)t)`T, then find
(a)n Frequency
(b) Wavelength
(c) Speed of the wave
(d) Expression for electric field part of electromagnetic wave

Explanation

(a) `f=(0.6xx10^(12))/(2pi)=9.55xx10^(0)Hz`
(b) `lambda=(2pi)/(k)=(2pi)/(0.2xx10^(4))=3.14xx10^(-3)m`
(c) `c=(omega)/(k)=(0.6xx10^(12))/(0.2xx10^(4))=3xx10^(8)(m)/(s)`
(d) `vecE=3xx10^(8)xx4xx10^(-8)sin(0.2xx10^(4)xx0.6xx10^(12)t)hat k (N)/(C)`
