Light coming from slit S1 makes distance r1to the screen. Light coming from slit S2 makes distance r2 to the screen. If the wave length is l, for the constructive interference r1 – r2have to be equal to
for constructive interference path difference should be equal to integral multiple of wavelength of light.
so. r1 - r2 = n × l
so it can be I and 3I
option E,. A and B
Please rate it up, Thanks!
Light coming from slit S1 makes distance r1to the screen. Light coming from slit S2 makes...
HELP ME PLEASE THANK YOU!!!!!
Light coming from slit S1 makes distance

A and B;
C and D.
Bright fringe S o S,
In each of the figures below, a light beam from hits a double slit plate with a separation of s or 2s. After that, it travels a distance until it hits a screen, creating an interference pattern on a screen. The interference pattern is shown on the diagram, where the constructive wave peaks are visible and the destructive wave troughs are not. The distance to the screen and the separation of peaks is given in the figure. Rank the wavelength...

In a double-slit experiment, a viewing screen is located 2.30m from the slits and the distance between the slits is 0.28mm. A monochromatic light with a wavelength of 4.80 ✕ 102 nm is directed toward the double slit and forms an interference pattern on the screen. Find the distance (Delta y in mm) between the first and second bright fringes of the interference pattern. a. None of the given answers b. 3.94 c. 7.89 d. 11.8 e. 0.25 f. 1.97
2. A double slit system has a slit spacing of 15um and a slit-to-screen distance of 2.2 m. The m-1 maxima in the interference patter occurs 7.1 cm from the screen center. What is the wavelength of the light used in the experiment?
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...

A screen is separated from a double-slit source by a distance L. When light of wavelength 563 nm is incident on the double slit, the separation distance between adjacent bright fringes on the screen is 0.0370 mm. When instead, 500 nm light is used, what is the separation distance (in mm) between adjacent bright fringes?
In a double-slit interference pattern, light from the top slit travels a distance of 4.0 m between the slit and a point on the screen.
