- Red light has an magnetic field component amplitude Bm = 8 μT, and wavelength λ= 440 nm - calculate the frequency of the light3.Which wavelength range does the green line of the mercury lamp belong to: 600-700 nm, 500-600 nm, or 400-500 nm, or 300-400nm?2. (a) Write general complex exponential expressions for two electric field waves (1 and 2) shown below. Both are plane waves with the same wavelength 2, frequency w, and polarization. (b) Derive an expression for the irradiance (I) of the combination of these two fields.
