A beam of yellow light with a wavelength of 06 pm is normall

A beam of yellow light with a wavelength of 0.6 pm is normally incident upon a glass surface. If the surface is situated in the plane z greaterthanorequalto 0 and the relative permittivity of glass is epsilon_r2 = 2.25, determine the locations of electric field standing wave maxima in air as measured from the interface. Assume that eta = 1 20 pi ohm. and eta_2 = 80 pi ohm, giving a reflection coefficient of gamma = -0.2. z\' = 0.3m mum, n = 0,1, 2,... z\' = (0.15 + 0.3n) mum, n = 0,1, 2,... z\' = (0.3 + 0.6n) mum, m = 0,1, 2,... z\' = (0.6 + 0.3n) mum, n = 0,1, 2,...

Solution

z = (2n +1)d/2

n = 120-80/200=0.2

relative permealibility = e1/e2*wavelength
