Evaluate each of the following as true or false?
true false White light is monochromatic.
true false The reflected component of light traveling
from one medium into another of lower refractive index will under
go a phase change of 180 degrees relative to the incoming
light.
true false Constructive interference occurs when two
waves differ in phase by 180 degrees.
true false A phase difference of 360 degrees is the same
as a path difference of one wavelength.
true false Monochromatic light has one frequency.

Light with wavelength 590 nm in air is incident perpendicularly from air on a film 8.71 um thick and with refractive index 1.35. Part of the light is reflected from the first surface of the film, and part enters the film and is reflected back at the second surface, where the film is again in contact with air. (a) How many waves are contained along the path of this second part of the light in its round trip through the...

Indicate true or false in each of the following statements: A standing wave is the superposition of two waves The beating of two waves can be heard as a much higher frequency than the sum of the two frequencies. The second harmonic is twice times the frequency of the fundamental. Constructive interference occurs when the phase difference of two otherwise identical waves is 2π or multiples thereof. A node is a position on a standing wave of maximum displacement

Plane coherent light waves with wavelength 565 nm are incident on two narrow parallel slits positioned a distance d = 1 mm apart in a plane parallel to the incoming wavefronts. The interference pattern is observed on a screen parallel to the original wavefronts at 1 m from the two slits. One of the slits is covered on the illuminated side by a glass slide of 0.1 mm thickness with refractive index 1.5. a/ What is the phase difference ∆φ...

In a double-slit experiment, the slits are illuminated by a monochromatic, coherent light source having a wavelength of 697 nm. An interference pattern is observed on the screen. The distance between the screen and the double-slit is 1.67 m and the distance between the two slits is 0.104 mm. A light wave propogates from each slit to the screen. What is the path length difference between the distance traveled by the waves for the fifth-order maximum (bright fringe) on the...
