Light of wavelength 562 nm is used to illuminate normally two glass plates 21.8 cm in length that touch at one end and are separated at the other by a wire of radius 0.02 mm. How many bright fringes appear along the total length of the plates.
Light of wavelength 526 nm is used to illuminate normally two glass plates 20.2 cm in length that touch at one end and are separated at the other by a wire of radius 0.024 mm. How many bright fringes appear along the total length of the plates.
6. [15 ptsJTwo glass plates are 15.0 cm long. At one end they are in contact, at the other end they are separated by 0.03 mm. Assume normal incidence with a monochromatic light (wavelength in air is 50nm) a) Is the fringe at the line of contact bright or dark? Explain your answer. What is the spacing of the bright b) If the glass plates have n 1.6 and space between plates contains water (n 1.33). Is the fringe at...
A very fine wire 7.65×10?3 mm in diameter is placed between two flat glass plates. Light whose wavelength in air is 660 nm falls (and is viewed) perpendicular to the plates and a series of bright and dark bands is seen. Part A How far apart are the dark fringes if the glass plates are each 21.5 cm long? Express your answer to three significant figures and include the appropriate units. ?x =____ (units?)
A laser with a wavelength of 470. nm illuminates two narrow slits. The interference pattern from the double slits is viewed on a screen that is 3.30 m away. Over a distance of 41.0 mm there are 11.0 bright fringes with the first and last fringe situated exactly at each end of that distance. What is the spacing between the two slits?
A beam of 570-nm light passes through two closely spaced glass plates at close to normal incidence as shown in the figure below. For what minimum nonzero value of the plate separation d is the transmitted ight bright? nm
Thin film examples Suppose the two glass plates in the figure are two microscope slides 10 cm long. They are in contact at one end and are separated by a piece of paper 0.020 mm thick at the other end. What is the spacing of the interference fringes seen by reflection? Is the fringe at the line of contact bright or dark? Assume monochromatic light with λ-500 nm. λο 500 nm h - 0.020 mm 1 10.0 cm
please show all work wavelength 450 nm? 8. Monochromatic light illuminates two parallel slits 0.2 mm apart. On a screen I m away from the slits, the first bright fringe is separated from the central fringe by 2.5 mm. Find the wavelength of the light. C
Laser light with a wavelength λ = 670 nm illuminates a pair of slits at normal incidence What slit separation will produce first-order maxima at angles of ±± 25 ∘∘ from the incident direction?
