Young's double slit experiment is one of the quintessential experiments in physics. The availability of low cost lasers in recent years allows us to perform the double slit experiment rather easily in class. Your professor shines a green laser (560 nm) on a double slit with a separation of 0.114 mm. The diffraction pattern shines on the classroom wall 3.0 m away. Calculate the fringe separation between the third order and central fringe.

A diffraction grating is 3 cm long and has 3000 slits. White light shines through it and creates fringes on a screen 0.7 m away. The first fringe of the color pewter appears 3.4 cm from the central white fringe. What wavelength is this pewter light (in nanometers, nm)

tow slit experiment. function at slit 1 acquires an arbitrary in a wave random phase that is to be overaged over. the total wave function at th screen is Y Cxxt) = e9 4, Cxit) +4z Cxrt) show that under these circumstances the interference averages out %3D

An experiment is setup to measure the diameter of the sphere in the diagram using sizing measurements based on interference. A thin piece of glass slab is placed one side of a highly reflective substrate. A yellow light created by Sodium wavelength = 589.3nm having a normally incident. Fringes can be observed on the glass from the interference. With a gap between the two bright fringes is measured to be g = 0.118mm, with an overall length for the setup to be L = 20mm. The setup will be placed in air having n = 1. What is the diameter of the sphere? W

** 38. Two plastic plates (index of refraction n = 1.3) are separated by an air gap of 0.9 µm. Analyze the reflections of light of wavelength 600 nm and conclude whether it will be brightly reflected or not. 0.9 um gap ** 39. The air gap in the previous problem is now filled with a mineral oil whose index of refraction is n = 1.5. Analyze the reflections of light of wavelength 600 nm and conclude if it will be brightly reflected or not.

You perform a double-slit experiment in order to measure the wavelength of the new laser that you received for your birthday. You set your slit spacing at 1.05 mm and place your screen 8.51 m from the slits. Then, you illuminate the slits with your new toy and find on the screen that the tenth bright fringe is 4.63 cm away from the central bright fringe (counted as the zeroth bright fringe). What is your laser's wavelength i expressed in nanometers? = nm

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 picture shows the interference pattern obtained in a double-slit experiment with monochromatic light of wavelength 650 nm. The distance shown between intensity maxima is y = 4 mm.    How far away (in mm) from the central maxima is the location where the two waves have a path difference of exactly 1950 nm?

Consider a laser light illuminating a vertical thin film of polystyrene (n=1.55) of thickness t= 85 nm The thin film is surrounded by air. What should the wavelength of the laser be to observe a bright interference O lambda=403 nm O lambda=527 nm lambda=566 nm lambda= 75 nm lambda=371 nm

Laser light at 600 nm falls on a double-slit apparatus with slit separation 6 μm. Find the separation between the following fringes as seen on a screen 1 m from the slits. (a) The first and second bright fringes. (b) The third and fourth bright fringes.
