Monochromatic light of wavelength, λ is traveling in air. The light then strikes a thin film having an index of refraction n1 that is coating a material having an index of refraction n2. If n1 is larger than n2, what minimum film thickness will result in minimum reflection of this light?
| A | B | C | D | E | F | G | H | I | J |
| A | λ/(4n2) |
| B | λ/n2 |
| C | λ/(4n1) |
| D | λ/(2n1) |
| E | λ/4 |
| F | λ |
| G | λ/2 |
| H | λ/(2n2) |
| I | λ/n1 |
| J | The correct response is not shown above |

Monochromatic light of wavelength 560 nm strikes a thin layer of soap, which has an index of refraction of 1.4 and rests on a bathroom tile. (a) If the layer of soap is 700 nm thick, does constructive interference, destructive interference, or partial interference occur when the light strikes the surface close to the normal? (b) What is the minimum thickness of soap that would result in no (or minimal) reflection from the surface? (100 nm)

(25 points) The figure below shows a thin film, of a transparent material of thickness d and index of refraction nfwhere n2 > nf > n1. Monochromatic light of wavelength 600nm is incident onto the thin film. a. For what three smallest film thicknesses, d, will reflected light-rays-1 and -2 interfere constructively? b.

The reflection of light from the thin film of thickness t as
shown in the figure appears violet (400nm) when viewed from above.
This means the two rays reflecting off of the two surfaces
interfere constructively. t is the minimum thickness. The dark grey
material has a higher index of refraction than the light grey with
the white being air. For what minimum thickness relative to t would
it need to be for the film to now appear red (700nm)...
