Two flat plates of glass with parallel faces are on a table, one plate on the other. Each plate is 11.2 cm long and has a refractive index of 1.55. A very thin sheet of metal foil is inserted under the end of the upper plate to raise it slightly at that end, in a manner similar to that pictured in the figure (Figure 1). When you view the glass plates from above with reflected white light, you observe that, at 1.10 mm from the line where the sheets are in contact, the violet light of wavelength 410 nm is enhanced in this reflected light, but no visible light is enhanced closer to the line of contact.

A thin film with a thickness of 460 nm is sandwiched between air and glass with refractive index of 1.56 as shown in Figure 4 below. The thin film is illuminated with a beam of white light which is perpendicular to the film and consists of the full range of wavelength for the visible spectrum. air n glass Figure 4 (a) For reflective interference, light with a wavelength of 650 nm undergoes fully constructive interference. Find the refractive index n of the film. (Assume the refraction index n is between 1 and 2.) (b) At what visible wavelength does the reflected light undergo fully destructive interference.
The index of refraction of water is 1.33. If you (or a fish) were under calm water swimming in the daytime, looking upward you would see a bright circle of light above you at the surface. The circle is because of total internal reflection, and the boundary is where light from below is totally reflected if it is beyond the boundary. What would you see just at the inside edge, where there is the light of the sky coming in? Hint: Camera lenses that produce this effect are called "fisheye" lenses. An image of yourself, because of the law of reflection. Directly overhead, probably the Sun, because the rays in air at that point are perpendicular to the surface. The horizon of the pool or lake, because rays in the air at that position are horizontal and parallel to the surface. The bottom of the lake, reflected in the water., because of total reflection.
Transmission through thin layers. In the figure, light is incident perpendicularly on a thin layer of material 2 that lies between (thicker) materials 1 and 3. (The rays are tilted only for clarity.) Part of the light ends up in material 3 as ray r3 (the light does not reflect inside material 2) and r4 (the light reflects twice inside material 2). The waves of rz and r4 interfere, and here we consider the type of interference to be either maximum (max) or minimum (min). The table below provides the indexes of refraction ng, n2, and n3, the type of interference, and the thinlayer thickness L in nanometers. Give the wavelength that is in the visible range.
