Visible light strikes plain glass in air, with a refractive index of n = 1.5. For 4 lenses, each with two surfaces (front and back), determine the following:
i. What percentage of light is reflected from a single surface when light passes from air (n = 1.0) into glass (n = 1.5)?
ii. After passing through 4 lenses (8 surfaces), what percentage of light is transmitted? Determine the total transmitted light after passing through all lenses.
Hint: Use the formula for reflection at normal incidence R=(n1+n2n1−n2)2.
