<s>[INST] An electromagnetic wave is traveling with speed of light equal to 3 x 10^8 m/s in the free space and is consisting of radiations of three different wavelengths λ1= 200 nm, λ2 = 400 nm and λ3 = 4000 nm. If E is the amplitude of the electric field of the wave, then find out the amplitude of the magnetic field of the wave.[/INST]
