Light of wavelength 600 nm passes through two slits separated by 0.20 mm and is observed on a screen 1.0 m behind the slits.
the location of the central maximum is marked on the screen and labeled y=0. (i only need on the last 2 parts, but i will list all of them in case information from them is needed to complete the last parts.)
a. at what distance, on either side of y=0, are the m=1 bright fringes?
b. a very thin piece of glass is then placed in one slit. because light travels slower in glass than in air, the wave passing through the glass is delayed by 5.0x10^-16 s in comparison to the wave going through the other slit.
what fraction of the period of the light wave is this delay?
c. with the glass in place, what is the phase difference, [delta phi][/0], between the two waves as they leave the slits?
d. the glass causes the interference fringe pattern on the screen to shift sideways. which way does the central maximum move (toward or away from the slit with the glass) and by how far?

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
