A thread must have a uniform thickness of 0.525 mm. To check the thickness of the thread, you can illuminate it with a laser of wavelength 625.8 nm. A diffraction pattern like the one produced by a single slit forms on a screen. a. If the screen is 3.00 m from the thread, how far apart are the fifth-order minima from one another? b. If the thread's thickness increases by 20%, how far apart will the fifth-order minima be?

(a) Whatis the path length difference corresponding to the fourth darkband? (b) What is the distance on the screen between the centralbright band and the first bright band on either side of the centralband? (Hint: The angle to the fourth dark band and the angle tothe first bright band are small enough that tan u = sin u.)

(Convert your result so the angle is between 0 and 360°.)
The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red) and 486 nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 460 lines/mm , and the light is observed on a screen 1.5 m behind the grating. What is the distance between the first-order red and blue fringes? Express your answer to two significant figures and include the appropriate units.
Please explain each step....You shine monochromatic light with wavelength 720 nm through a slit that has a width of 0.750 mm and observe a diffraction pattern on a screen that is 3.60 m from the slit. 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.

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. 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=________
