1) A soap bubble (n = 1.33) is floating in air.

1) A soap bubble (n = 1.33) is floating in air. If the thickness of the bubble is 115 nm, what is the wavelength of the light that is most strongly reflected? (Assume light is hitting the bubble nearly normal to the surface.) 2) An air wedge is formed between two glass plates (n = 1.5) separated at one edge by a very fine wire (see figure). When the wedge is illuminated from above by a light with a wavelength of 600-nm, 30 dark fringes are observed across the plates. Calculate the radius of the wire
