please answer question d and e only, thank you
d. There are 5 slits, the the phase difference between two consecutive slits be and amplitude of light from individual slits be a.
Then amplitude of light due to all slits
Central maxima is at 7cm, for that
For primary maxima, just before 'a', (As it is a primary maxima, light from all slits should be in phase)
For point 'a', should be greater than
amplitude=0
As, should be just greater than
So, the very first value after is
So, the path difference,
e.

1. The picture below shows the intensity as a function of angle (in degrees) for a 2-slit interference pattern. You can assume that the gridlines are spaced by 1 degree on the horizontal axis. a. Assuming we are using 633 nm laser light, what is the approximate slit spacing? b. Recall that the 2-slit intensity pattern is pinched to zero by the diffraction pattern created by the slit width. Approximately how wide are the slits? asin θ ηλ gives the...
The below interference/diffraction pattern for two slits is observed on a screen that is 1.5 meters from the slits. Here, red light with a wavelength of 700 nm (7.0x10-7 m) that is normally incident on these slits yields this pattern. 9 mm 4 mm Using the locations of interference maxima (e.g., the m-2 maxima lies 4.0 mm from the center of the pattern), determine the distance between these two slits (in millimeters). For the above pattern, using the location of...

4) Interference and Diffraction Phenomena (10 points) (a) In a single slit diffraction experiment with a screen far away from the slit, with waves of wavelength 1, there will be no intensity minima if the slit becomes too small compared to the wavelength. What is the minimum slit width (in terms of ) for which no intensity minimum occurs? (Note: if there is no minimum, the screen looks essentially fully illuminated. Think what condition that puts on the angle of...
Consider double slit experiment with two slits are separated by d=0.715 mm and each slit width is 0.00321 mm. Screen is placed L=1.28 m away from the slits. a) Derive an algebraic equation to find linear distance of interference bright fringe on the screen from central bright (central maxima) fringe? b) Consider interference pattern due to light of unknown wavelength and linear separation between 2 and 5" bright fringes is 3.05 mm.

PART 2: Multiple slits - Interference Remove the single slit disk, and install the multiple slit disks. You will now sements as in part 1 to explore the nature of the multiple slit interference patit this case, however, you will mark the maxima, not the minima. Siit disks. You will now do much the same Use the double slits of separation d = 0.25 mm (and a = 0.04mm). Increase distance L ben the screen and the slit as much...
Problem 7 (20 points): Each graph below shows the relative intensity versus 0 for a double slit experiment. The horizontal scale is the same for all graphs. The only possible differences among the cases are the values of the slit width (a) and distance between the centers of the slits (d). Case For each of the three cases, calculate the ratio- a) 0.5 b) Rank the cases according to distance between the centers Case 2 of the slits (d), from...
The single-slit diffraction pattern shown in the Figure was produced with red light of wavelength lambda = 633 nm. The screen on which the pattern was projected was located a distance D = 2.0m from the slit. The slit has a width of a = 0.30mm. What is the width w of the central maximum? (The width is equal to the distance between the two first diffraction minima located on either side of the center.)
