Two point sources (S1 and S2) emit light in phase with a wavelength of 600nm and the same amplitude. A detector P is shown on the x axis, which extends through the source S1. The phase difference between the light arriving at P from each of the two sources is recorded as P is shifted indefinitely to the right along the x axis from x=0.The result is displayed in the graph below, whose horizontal scale is not specified. What is the position of the penultimate intensity minimum detected by P? a)6,75µm b)40,5µm c)71,5µm d)1,05µm e)21,5µm

You measure three segments of the distance between a diffraction slit an the screen on which the pattern forms: x1 = (15.8 ± 0.2) cm, x2 = (6.7 ± 0.1) cm, and x3 = (11.3 ± 0.1). What is the uncertainty of the total distance x1 + x2 + x3? Group of answer choices 0.4 cm 0.5 cm 0.2 cm 0.3 cm 0.1 cm

The ship in the figure below travels along a straight line parallel to the shore and a distance d = 700 m from it. The ship's radio receives simultaneous signals of the same frequency from antennas A and B, separated by a distance L = 810 m. The signals interfere constructively at point C, which is equidistant from A and B. The signal goes through the first minimum at point D, which is directly outward from the shore from point B. Determine the wavelength of the radio waves.

The attatched figure shows a Michelson interferometer with a movable mirror M1, a fixed mirror M2, and a beam splitter Ms , which is a half-silvered mirror that transmits one-half the light and reflects one-half the light incident upon it independent of the direction of the light. The source emits monochromatic light of wavelength λ.  Assume the beam splitter introduces a phase change of π for light that follows path 1 from the source to the detector relative to light that follows path 2 from the source to the detector. Also assume the mirrors M1 and M2 reflect 100% ofthe light incident upon them and the photodetector PM (a photomultiplier) is 100% efficient as well. Question:  Use the principles of quantum mechanics to determine the probability that a photon entering the interferometer is detected by the photodetector. Express your answer in terms of the lengths I1 , I2 and λ. Find an expression for I1 in terms of I2 and λ, such that there is 100% probability that the photon is…

Two antennas located at points A and B are broadcasting radio waves of frequency 104.0 MHz. The signals start in phase with each other. The two antennas are separated by a distance d = 8.7 m. An observer is located at point P on the x axis, a distance x = 110.0 m from antenna A. The points A, P, and B form a right triangle. Now observer P walks along the x axis toward antenna A. What is P's distance from A when they first observe fully constructive interference between the two waves?

In the figure, two isotropic point sources of light (S1 and S2) are separated by distance 3.20 µm along a y axis and emit in phase at wavelength 900 nm and at the same amplitude. A light detector is located at point P at coordinate xp on the x axis. What is the greatest value of xp at which the detected light is minimum due to destructive interference? y S2 Number i Units

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? Please keep one decimal place in your answer. (c = 3.00 × 108 m/s)
