12. Hypothesis: A sheet of cardboard that is two inches thick will block the WiFi signal from a router. Multiple thicknesses of cardboard are used, including a 0.25 inch-thick sheet, a 0.5
inch-thick sheet, a 1 inch thick sheet, a 1.5 inch-thick sheet, and a 2 inch thick sheet. Each sheet is 4 feet by 4 feet square, and the sheets are placed in the same location for each
test. A computer is used to detect the WiFi signal, and it is kept in the same location for each test. The same program is used to test the strength of the signal. Three data points are
collected for each thickness of cardboard. Would the results of this experiment be reliable? Why do you think so?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
