In solar cells, a silicon solar cell `(mu = 3.5)` is coated with a thin film
of silicon monoxide `SiO (mu = 1.45)` to minimize reflective losses from the surface.
Determine the minimum thickness of SiO that produces the least reflection at a
wavelength of 550nm, near the centre of the visible spectrum. Assume
approximately normal incidence .

On face of a glass (mu = 1.50) lens is coated with a thin film of magnesium fluoride MgF_(2)(mu = 1.38) to reduce reflection from the lens surface. Assuming the incident light to be perpendicular to the lens surface. The least coating thickness that eliminates the reflection at the centre of the visible spectrum (lamda = 550 nm) is about

A glass lens is coated on one side with a thin film of magnesium fluoride (MgF_(2)) to reduce reflection from the lens surface (Fig. 2.26). The Index of refraction of MgF_(2) is 1.38, that of the glass is 1.50. What is the least coating thickness that eliminates (via interference) the reflections at the middle of the visible specturm (lambda = 550nm) ? Assume that the light is approxmately perpendicular to the lens surface.
