Textbook Question
Chapter 14, Problem 9MCQ
Several air bubbles are present in water flowing through a pipe of variable cross-sectional area (Figure Q14.9). What happens to the volume of an air bubble when it arrives at the narrow part of the pipe, where the cross-sectional area is half that of the wider part? Assume the temperature of the gas in the bubble stays constant.
a. The volume of the bubble remains unchanged because water is incompressible.
b. The volume of the bubble remains unchanged because the temperature of the gas in the bubble is constant.
c. The volume of the bubble decreases because the pressure in water increases.
d. The volume of the bubble increases because the pressure in water decreases.

6. Bending a lens in OpticStudio or OSLO. In either package, create a BK7 singlet lens of 10 mm semi-diameter
and with 10 mm thickness. Set the wavelength to the (default) 0.55 microns and a single on-axis field point at
infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens
is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to
calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length
of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis
tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from
diffraction limited, with a spot size of more than 100 microns.
Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert
one extra line at the top of the merit function. Assign the…
