- At what angle do you observe the 4th order maximum relative to the central maximum when 400 nm light is incident normally on two slits separated by 0.025 mm? Also, At what angle do you observe the 3rd order minimum? Set-up is the same as above and with a slit separation of 0.025 mm. Make sure to answer both parts of the question. Show all work.arrow_forwardThe analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation. Apply your understanding by interpreting the following statements and identifying the values of y, d, m and L. Finally, perform some conversions of the given information such that all information share the same unit. a. Two slits separated by 0.250 mm produces an interference pattern in which the fifth dark band is located 12.8 cm from the central antinode when the screen is placed a distance of 8.2 meters away. y= ________ d=________ m=_______ L=________arrow_forwardThe analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation.

Finally, perform some conversions of the given information such that all information share the same unit.

- In a double slit experiment, the distance between the slits is 0.2 mm and the distance to the screen is 100 cm. What is the phase difference (in degrees) between the waves from the two slits arriving at a point 5 mm from the central maximum when the wavelength is 400 nm? (Convert your result so the angle is between 0 and 360°.)arrow_forwardYou just won a brand new laser pen and you want to know the wavelength of the light, so you set up Young’s double-slit experiment and observe the interference pattern on screen 1.2 meters away from the slits. The slits are 0.25 mm apart and you measure the distance between the centers of the first dark fringes on either side of the central maximum to be 3 mm. What is the wavelength of your new laser? If visible, what color should it appear, if not visible state the region of the EM spectrum? Hint: Draw a picture.arrow_forwardLaser light with a wavelength of 632.8 nm is directed through one slit or two slits and allowed to fall on a screen 2.60 m beyond. as shown the pattern on the screen, with a centimeter ruler below it. (a) Did the light pass through one slit or two slits? Explain how you can determine the answer. (b) If one slit, find its width. If two slits, find the distance between their centers.arrow_forward
- The analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation. Apply your understanding by interpreting the following statements and identifying the values of y, d, m and L. Finally, perform some conversions of the given information such that all information share the same unit. An interference pattern is produced when light is incident upon two slits that are 50.0 micrometers apart. The perpendicular distance from the midpoint between the slits to the screen is 7.65 m. The distance between the two third-order antinodes on opposite sides of the pattern is 32.9 cm. y= ________ d=________ m=_______ L=________arrow_forwardHow much diffraction spreading does a light beam undergo? One quantitative answer is the full width at half maximum of the central maximum of the single-slit Fraunhofer diffraction pattern. You can evaluate this angle of spreading in this problem. (a) as shown, define φ = πa sin φ/λ and show that at the point where I = 0.5Imax we must have φ = √2 sin φ. (b) Let y1 = sin φ and y2 = φ = /√2. Plot y1 and y2 on the same set of axes over a range from φ = 1 rad to φ = π/2 rad. Determine φ from the point of intersection of the two curves. (c) Then show that if the fraction λ/a is notlarge, the angular full width at half maximum of the central diffraction maximum is θ = 0.885λ/a. (d) What If? Another method to solve the transcendental equation φ = √2 sin φ in part (a) is to guess a first value of φ, use a computer or calculator to see how nearly it fits, and continue to update your estimate until the equation balances. How many steps(iterations) does this process take?arrow_forwardDuring a super-cool experiment, an optical engineer wanted to decide on the best components to use for constructing an instrument. The engineer is requesting your help in finding the following importing information. What is the slit spacing of a diffraction grating that will be necessary so that 600-nm light will produce a first order principal maximum at 25.0° away from the centerline? Please explain your reasoning. If the distance between the grating and the screen is 5.00 m, what is the distance, on the screen, between the first order bright fringe and the third order bright fringe when the same 600-nm light source is used? Please explain your process.arrow_forward

The intensity at the center of the central maximum is Io = 7.80 W/m2. What is the intensity of the light at a point on the pattern that is halfway between the center of the central maximum and the first minimum of interference? The purple line in the figure shows the points that are halfway between the center of the central max. and the first min.arrow_forwardConsider a single slit that produces its first minimum for 630 nm light at an angle of 26 degrees Part a: How wide is the single slit in meters? Part b: at what angle ( in degrees) will the second be minimumarrow_forwardAn intereference pattern is produced by light with a wavelength of 560 nm from a distant source incident on two identical parallel slits seperated by a distance (between centers) of 0.580 mm.
