Wordle.net tag cloud for interesting topics covered in Midterm 1, generated by responses from Physics 205B students at Cuesta College, San Luis Obispo, CA (http://www.wordle.net/show/wrdl/7700708/Untitled).

Students have a weekly online reading assignment (hosted by SurveyMonkey.com), where they answer questions based on reading their textbook, material covered in previous lectures, opinion questions, and/or asking (anonymous) questions or making (anonymous) comments. Full credit is given for completing the online reading assignment before next week's lecture, regardless if whether their answers are correct/incorrect. Selected results/questions/comments are addressed by the instructor at the start of the following lecture.

List at least five words describing interesting subjects covered in class (up through this midterm). (Graded for completion.)

Describe your most interesting subject, and briefly explain why this subject interested you. (Graded for completion.)

The following are all of the student responses, verbatim and unedited.
"I enjoyed learning about single slit and double slit interference and how they relate to things like CDs/DVDs and even how you can determine the width of a strand of hair using these principals I really like the ray diagrams because you can draw it right and get the answer."

"Something interesting is myopia, hyperopia, and how being nearsighted or farsighted needs corrective lenses that are convergent or divergent."

"I actually like the ray tracing part of this midterm. It seemed complicated at first, but the many different parts make it more interesting."

"destructive interference. I don't quite know why, but I was super interested in this topic. Light fascinates me and its so interesting how it can cancel itself."

"Definitely diffraction and total internal reflection"

"Corrective optics was the most interesting to me because I wear contacts. It was interesting to find out what kind of lens I wear and I realized that my vision is very bad because my prescription is -4.75 diopters."

"I personally found polarization very interested in the way that it works and the amount of light transferred."

"The most interesting subject covered in this midterm would have to be constructive vs. destructive interference for me. It interested me because it was a subject I was able to really grasp the best."

"i really enjoyed learning about light refraction. I think that it is interesting that you could think something is not where it actually located due to light. also polarization. i forgot to order the polarized lenses for my glasses no i see the lens glare."

"Little here has direct application to my major beyond perhaps polarization, but getting to the start of electricity has the most personal interest to me for hobbyist purposes."

"Optics. Although I could relate most everything covered to 'real life', I really had no idea how any sort of lenses worked, and, of course, I use them a lot."

"I enjoyed learning about the relationship between the wavelength, frequency, and speed of light. This interested me in part because I could understand it and how they effect each other when altered."

"The most interesting subject covered in the midterm are the lens problems. I find this subject interesting because it was easy to follow once I was able to understand the basic concept of the equation and how it functioned."

"I like energy fields because they make sense to me"

"Interference (constructive and destructive). I think it's really cool how waves can be amplified and demolished to theoretically nothing by changing distance or putting the waves in or out of source. Also, how the concept applies to slit interference and creates the minimas and maximas."

"I enjoy learning about electric fields, because it makes the most sense to me and I feel as if it has a lot of 'real world' applictions"

"Think the most interesting topic we have covered this far, for me personally anyways, would have to be how light travels through a diverging and converging lens, with the ray tracings being my main center of focus. They made no sense whatever in my mind starting out, but once I figured out how to use the ruler properly and determine where each line went, based on whether it was converging or diverging, I experienced the greatest sense of satisfaction at having discovered something completely new and foreign to me."

"I thought total internal reflection was really interesting, I think it's really cool why diamonds are so awesome."

"The most interesting subject covered in this midterms is optics. Luckily it is interesting to me because I work at an optometrist office and will be going to optometrist school. This information helps me understand corrective optics. I have also had to wear corrective lenses since grade school so this stuff is relevant to my vision accuracy."
