020 10.0 points A hair is placed at one edge between two flat glass plates 7.45 cm long. When this arrangement is illuminated with 657 nm light, 131 bands are counted, starting at the point of contact of the two plates. How thick is the hair? Answer in units of m.
A hair is placed at one edge between two flat glass plates 10.7 cm long. When this arrangement is illuminated with 619 nm light, 132 bands are counted, starting at the point of contact of the two plates. How thick is the hair? Answer in units of m. I've tried 4.054E5 and got it wrong
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...
Two flat panes of glass (80 cm long, 15 cm wide, 4 mm thick) are on your lab table directly under a nearly monochromatic (wavelength 650 nm) light source. At one end one pane is resting on the other; at their other ends they are separated by a single thickness of paper. You notice that the light is strongly reflected only in multiple bands occurring one every 2.5 cm. How thick. is the paper?
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
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...
Suppose the two glass plates in are two microscope slide l=12.0cm long. At one end they are in contact; at the other end, they are separated by a piece of paper h = 0.022 mm thick. What is the spacing of the interference finger's seen by reflection. Part A: Practice Problem: Suppose that we use two layers of paper, so that h = 4.40timesIU^5 m. What is the fringe spacing?
Consider a thin film of silicon grease (n=1.5) between two flat
microscope slides having length L=10cm. The top slide is made of
plastic (n=1.4) and the bottom slide is made of glass (n=1.6). at
one end the slides are in contact and at the other end they are
separated by a wire that has width h=.02mm. Assume we are using a
monochromatic light source of wavelength
=500nm.
what is the spacing between the dark fringes?
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...
Question 6:
What percentage error would result from miscounting
the bars by one?
