COMMENTS ON TENTH PROBLEM SET - SPRING 2003

	This problem set should be done fairly directly, based on the
	lectures.  Of course, it's important to keep the variables and
	parameters straight, as many paramters have similar symbols,
	and to be aware of what approximations are being used where.

	It should be noted that the expressions given in lecture for
	the positions of secondary maxima for interference and
	diffraction patterns are approximations, as are the
	expressions for finding widths.  A more rigorous treatment
	would be of questionable validity (I've tried it), and a
	numerical treatment using MAPLE may be seen in a worksheet
	downloaded from the main ESG-8.03 page.

	10.1  There's no really good reason for MIT students not to
           use a computer with graphing capabilities for this one.  A
           simple calculation is needed for part (c).

	10.2  This is done fairly easily if the notation used in
           lecture May 7 is used for the problem.

	10.3  A similar problem was partly done in lecture.  Keep in
           mind that you're given the wavelength of 500 nm and the
           distance "R" from the source to the screen of 3 m.  Doing
           the parts in order is recommended but not mandatory.

	10.4  A practical application of much that was presented and
           demonstrated in lecture May 7.  Part (b) was not addressed
           directly, but the way to the answer should be seen after a
           few moments' reflection.
