A glass lens is coated on one side with a thin film of magnesium fluoride (MGF2) to reduce reflection from the lens surface as depicted in figure below. Determine the least coating thickness that eliminates (via interference) the reflections at the middle of the visible spectrum (A = 450 nm). Assume that the light is approximately perpendicular to the lens surface.

Rainbows are caused by dispersion in water droplets. Suppose that water has an index of 1.331 for red light (660 nm), and 1.342 for violet light (410 nm). White light is incident on water with an angle of incidence of 64.8 degrees. Inside the water, the white light is separated into its constituent colors. What is the difference between the angle of refraction of the red light and that of the violet light? This is a measure of the amount of dispersion, in the water. Give your answer in degrees.
White light originates in water (n = 1.33) and then passes through crown glass, which has mild dispersion behavior (nred = 1.52, nviolet = 1.53). What initial angle above the horizontal in water would be required for the glass to refract red light but internally reflect the violet light? Assume the glass is in contact with air above it. What would be the angle of refraction for red light at the glass-air interface? Air Glass Water

Interference effects are produced at point P on a screen as a result of direct rays from a 500-nm source and reflected rays offa mirror, as shown in Figure P24.67. If the source is L = 100 m to the left of the screen and h = 1.00 cm above the mirror, find the distance y (in millimeters) to the first dark band above the mirror.

A coating is being applied to reduce the reflectivity of a pane of glass to light with a frequency of 4.14 × 10¹4 Hz that is incident normally on the pane. If the material has an index of refraction of 1.34 and the glass has an index of refraction of 1.537, what is the minimum thickness the coating should have in nanometers?

A glass sheet measuring 15.0 cmcm ×× 29.0 cmcm is covered by a very thin opaque coating. In the middle of this sheet is a thin, straight scratch 0.00125 mmmm thick, as shown in (Figure 1). The sheet is totally immersed beneath the surface of a liquid having an index of refraction of 1.41. Monochromatic light strikes the sheet perpendicular to its surface and passes through the scratch. A screen is placed under the liquid a distance 32.0 cmcm away from the sheet and parallel to it. You observe that the first dark fringes on either side of the central bright fringe on this screen are 23.0 cmcm apart. What is the wavelength of the light in air? Express your answer in nanometers.
