3. The glass plates in the figure are separated by a thin round filament. When the top plate is illuminated normally with a light of wavelength 570 nm, the filament lies directly below the fourth order bright fringe. What is the diameter of the filament? um
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...
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
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.
Two glass plates are separated by fine wires with diameters d1 = 0.0500 mm and d2 = 0.0520 mm, as indicated in the figure(Figure 1) . The wires are parallel and separated by a distance of 7.00 cm. If monochromatic light with λ = 569 nm is incident from above, what is the distance (in cm) between adjacent dark bands in the reflected light? (Consider interference only between light reflected from the bottom surface of the upper plate and light...
A broad source of light of wavelength 600.0 nm illuminates, at
normal incidence, two glass plates 132.0 mm long that touch at one
end and are separated by a wire 42.0 microns in diameter at the
other end. How many bright fringes appear over the 132.0 mm
distance?
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
Question 5:
How would dust and oil on the glass plates affect the
results?
EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a...
Monochromatic light of wavelength 528 nm is incident from the top onto an air wedge formed by two glass plates, as the drawing shows. At the point P, the 10n bright fringe can be seen. What is the thickness t of the air wedge at P? Incident light TITTII Side view of glass plates 2.772e-6 t = Number Units m the tolerance is +/-2%
