Question

Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. In the figure, a double-glazed window consists of two identical panes of glass ( ?g=1.50 ), each ?g=62.0 mm thick, separated by an air gap of ?a=49.6 mm . If light incident on the glass makes an angle of ?=40.00∘ with respect to the glass, find the shift in path Δ? as the light enters the room. Use ?a=1.00 for the index of refraction of air.
