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 r3 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 n1, n2, and n3, the type of interference, and the thinlayer thickness L in nanometers. Give the wavelength that is in the visible range. ng 14 n1 n2 n3 Туре L 1.76 1.59 1.52 max 413 MacBook Pro
In the figure shown below white light in air shines on an oil film that floats on water. When looking straight down at the film, the reflected light is red, with a wavelength of 650 nm. What is the minimum possible thickness of the film? the incident light is white light Again, although the rays have not been drawn perpendicular to the interface, that is just for clarity. The rays actually are perpendicular. air n= 1.00 al oil = ? n = 1.50 b water n = 1.33
A perfectly flat piece of glass (n = 1.50) is placed over a perfectly flat piece of black plastic (n = 1.20) as shown in the figure a. They touch at A. Light of wavelength 600 nm is incident normally from above. The location of the dark fringes in the reflected light is shown on the sketch of figure b. (a) How thick is the space between the glass and the plastic at B? (b) Water (n = 1.33) seeps into the region between the glass and the plastic. How many dark fringes are seen when all the air has been displaced by water? (The straightness and equal spacing of the fringes is an accurate test of the flatness of the glass.)

Like light waves, water waves emerging from two sources interferes in the space surrounding the sources to produce a pattern of nodes and antinodes lying along lines. The diagram at the right represents the interference pattern created by two water waves. The waves were created by two objects bobbing up and down in phase at the same frequency. Point P on the pattern is a distance of 34.0 cm from S1 and 23.8 cm from S2. Determine the wavelength (in cm) of the water waves.

Three polarizing plates whose planes are parallel are centered on a common axis. The directions of the transmission axes relative to the common vertical direction are shown in the figure below. A linearly polarized beam of light with plane of polarization parallel to the vertical reference direction is incident from the left onto the first disk with intensity Ii = 12.0 units (arbitrary). Calculate the transmitted intensity If when ?1 = 15.0°, ?2 = 39.0°, and ?3 = 59.0°. Hint: Make repeated use of Malus's law.If = units

A soap bubble shows strong colors due to interference of the light that reflects from the inner and outer boundaries of the thin soap and water film. Light striking the outer surface has a phase change on reflection of . That means that its phase is flipped when it goes from air to the water surface and back out. Light reflecting from the inner surface, where it is in water then comes to the boundary with air, does not change its phase. Suppose you see white light reflecting from a bubble as it increases its size. The film making the bubble gets thinner and thinner and the colors reflecting from it change. The bubble glows in colors that differ with the thickness of the soap film. As it gets even thinner, what will you see at the place in the film that will soon burst? In doubt, try an experiment with soapy water and make your own bubble. Look at the colors of a reflected white light when the bubble thins. Darkness. The light will destructively interfere and the…
