Problem 5For each part of the below question, choose one correct answer from the drop-down multiple-choicemenu box.Two parallel narrow horizontal slits in an opaque vertical screen are separated center to center by d = 7mm. These are directly illuminated by a plane wave from a filtered discharge lamp. Horizontal fringesare formed on a vertical viewing screen 9 m from the aperture plane. The center of the sixth bright bandis y = 26 mm above the center of the zeroth/central bright band.a)Xo=Determine the wavelength o of the light in air.b)If the entire space is filled with a medium of an index of refraction n = 1.426, where wouldthe sixth fringe now appear (find y)?y=

Given,Slit separation, Screen distance Order, Distance from sixth maxima to central fringe,…

An object is projected with initial speed v0 from the edge ofthe roof of a building that has height H. The initial velocity of the objectmakes an angle a0 with the horizontal. Neglect air resistance. The final speed v equals v1 when a0 equals a1. If a0 is increased, does v increase, decrease, or stay the same?
In an interference experiment using a monochromatic source emitting light of wavelength 1, the fringes are produced by two long, narrow slits separated by a distance d. The fringes are formed on a screen which is situated at a distance D >> d.Write down an expression for the fringe width w. Please use "*" for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. Use "lambda" (without the quotes) for 1 in the equation box. For example, use d*lambda for d2. Please use the "Display response" button to check you entered the answer you expect. w=
Monochromatic red light with a wavelength of 660nm is incident on a pair of narrow slits that are separated by a distance of 4.00×10^4 *m. A viewing screen is placed a distance of 120cm behind the slits to observe the intensity pattern of the light after passing through the slits. a) Relative to the center of the pattern, where is the center of the third bright fringe?
air 1. n = 1 [a] The figure shows a soap film of thickness dį in air. Light impinges on the film with an angle of incidence 01 and is reflected and refracted at the interfaces. Rays 1 and 2 represents reflected light, while rays 3 and 4 represent light that has been transmitted into the glass. soap \[c] n, = 1.33 |d [b] air n= 1 3 4 The bracketed letters (a], [b], and [c] indicate reflections at the air-soap, and soap-air interfaces. For which of these reflections does a phase change of n occur? Check all that apply. [a] [b] O (c)
If a soap bubble is 120 nm thick, what wavelength is most strongly reflected at the center of the outer surface when illuminated normally by white light? Assume that the index refraction of air is na 1 (the actual value is 1.0003) and the index refraction of soap is ns = 1.35.
a) At what angle is the first minimum for 550-nm light falling on a single slit of width 1.00 um? When i solve the question, there is no way i get the answer to be 33.4 deg. rather i get the sin-1 (0.55) = 0.58. IS the final answer wrong in the bartley and the test book or am i wrong?
