JEE Main 2022 Physics question
If electric field intensity of a uniform plane electro magnetic wave is given as = −301.6 V/m. Then, magnetic intensity of this wave in will be : [Given : Speed of light in vacuum , Permeability of vacuum ]
Answer: (3)
Solution
For a wave travelling along +z, = (ĉ , with ĉ = ẑ. Then ẑ and ẑ , so = (1/c)(−301.6 $ - 452.4 ) (kz - ω
