Two thin layers of material with different indices of refraction are coated on a glass plate.The outer first material has n₁ = 1.240,the inner second material has n₂ = 1.550,and the glass has n_glass = 1.62.If light is incident from air on the first layer,what is the phase change for light that reflects from the glass? A) 180° B) 0° C) 360° D) 540° E) 720°
