Solve the following problems on your own paper. Please:

• Show all work.
• Put a box around your final answer to each problem.
• Be sure proper significant figures (SF) used for all answers.
• Separate all solutions with a horizontal line on your paper.
• A random selection of five problems will be graded for 20 points each.
• Solutions for suggested odd problems can be seen by following links.
• Solutions for assigned problems will be linked from this page after the due date.

Chapter 35

#4

Use a place on the graph where the data cross an intersection of grid lines (as usual with these kinds of problems).

#14

Set d = 100 * (wavelength) and insert into equation 35-14. The wavelength will cancel, so you don't need it.

#16

Answer with 3 SF.

#36

Use all values for m starting at zero until you aren't getting any wavelengths in the specified range. For (b), you can save time by starting at m=3.

#38

The phase difference here is just from the extra distance, nothing from reflection.

#40

This has a similar set-up to sample problem 35-6. Try four or five different m values for each case and find the wavelength that is common to your two lists.

#60

This has the same set-up as problem #43 but now 2 reflections in addition to the extra distance. Use the exact same principles as for reflection cases.

#66

This has the same set-up as problem #49. Use m = 3.

Suggested problems from chapter 35:

1, 2, 3, 5, 6, 7, 9, 11, 13, 15, 17, 18, 19, 20, 21, 22, 23, 25, 26, 35, 37, 39, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 57, 58, 59, 61, 62, 63, 64, 65, 67, 68

Chapter 36

#2

This is similar to sample problem 36-1.

#6

There are shorter ways to do this, but one way to solve it is to set up equations for y(1) and y(5). Knowing that y(5) - y(1) has a definite value gives you 3 equations with 3 unknowns.

#20

This is similar to sample problem 36-3 and problem #22.

#24

Use equation 36-17 here to find D. The intensity depends inversely on the radius of the pattern squared.
