Question1

Two rectangular, optically flat glass plates (of index of refraction 1.46) are in contact along one end and are separated next to other end by a sheet of paper that is 58 μm thick. The top plate is illuminated by monochromatic light (of wavelength 583 nm). An interference pattern results from the reflection of this light by bottom surface of the top plate and the top surface of the bottom plate.

What is phase change as the light is reflected from the top surface of the bottom glass plate?

1. Δφ = 2 π

2. None of these

3. Δφ = π 2

4. Δφ = 0 5 . Δφ = π

Question2

Azelastine hydrochloride is an antihistamine nasal spray. A standard size container holds one fluid ounce (oz.) of the liquid. You are searching for this medication in a European drugstore and are asked how many milliliters (mL) there are in one fluid ounce. Using following conversion factors, establish the number of milliliters in a volume of 2.06 fluid ounces:

1 gallon (gal) = 128 oz., 3.785 x 10-3 cubic meters (m3) = 1 gal, 1 mL = 10-6 m3.
