Tucker, Travis Can we expect to have index of refraction and Planck's constant questions
on the test?
Russell, Kristin
I just wanted to say that posting the lecture notes online have
defintately helped me with the homework over the past two weeks.
McClure, Michael
I am just curious about something on the homework. On the last
question of HW6 you discuss the aurora borealis. Is it the different atoms (nitrogen,
oxygen, ect.) that make the different colors? Also, is it harmful to the health of an
individual to be bombarded by this amount of electrons if you were at the earths poles?
Sloan, Jacque I was thinking about TV's the other day and was wondering what happens
when the gets static on it? Does that have to do with the signals from the station or the
actual TV?
Jones, Kristin I think class is going great. The homeworks are a bit tedious at times
because they are mostly written response. I am not going to compain about this like most
people I am sure are, but rather I am going to say that they really help me to understand
the concepts. The only thing that is in writing them we could go for ever to make sure
that we get full credit. I think that it needs to be explained better what we have to write
to .5 credit point answers vs. 1 point credit answers. I hope this makes sense.
Wessels, Bobbie Jo (1) In terms of the reading quizzes, I prefer them at the end of
class. I mean I think you agree that the book doesn't do that good of a job teaching unless
it's tiny details which we never cover in class, so it's kind of silly to test us on a nearly
use-less material. Or the 2 out of 3 questions correct idea is nice too.(2)I really like how
you include the learning goals in the lecture. :) It gives us a good sense of where we're
going.(3) I really really really wish James or someone would e-mail us our grades
(participation, readin quizzes, test, and homework combined). I have no clue how to
calculate the former two and would really appreciate knowing how well I'm doing in
class. Thanks!-Bobbie Jo :)
McDermott, Margaret I really enjoy the help sessions. I attend on Friday afternoons and
Akiko always explains the concepts very well. Thank you for the help sessions and I
would like to thank her for all of her work!Maggie McDermott
Graham, Christopher The class lectures and homework seemed to go together really well
last week. There were no homework problems with concepts that we hadn't covered in
class, so I felt really prepared when I was doing it. I liked how we went into detail on
how televisions work. It was cool to find out how an entire device works instead of just
parts of it. One thing that I was really suprised about was that there's no such thing as a
photon that's not a pure light color. I would have guessed that photons could be any color
as long as their wavelength was different. Overall, I thought last week was really
interesting, and that the concepts were presented really well.
meynell, ben What color is the sun if I looked at it with my eyes from space? Would it
be "whitish", "yellowish" or a different "yellowish" than we see from earth?I heard that
the "yellowish" of our sun -- the way it looks to us from earth -- is primarily due to the
scattering of blue light in our atmosphere. For instance, assuming our sun is "whitish",
that would mean a mixture of red, green, and blue light would be coming toward the
earth. However, we lose some blue light in the atmosphere so that tips the scale more in
the favor of red and green. Red and green minus some blue makes a "yellowish" sun.I
guess I'm wondering how much of a difference is between the color of the sun we see
from earth vs. the color we would see from space.
Donlin, Siobhan
I was wondering if energy is conserved. Thanks.
Downing, Leigh
I think that what we learned last week about how our eyes interpret
color was really interesting. The questions on the homework regarding the simulation
were a good way for me to see how the eye views two or three wavelengths of color
together. I did have a few concerns about the homework though. First, there were a lot
of essay questions and many were in-depth. In our previous homeworks, the last question
has been more in-depth, but in this homework it was many questions. I also had a
problem getting help with the homework. When I went to the help session on Tuesday,
the two learning assistants debated on the answers to some of the questions and I had to
decide what to write becaues they couldn't completely agree on what the answers to some
of the questions were. It is really hard to go get help and then the helpers don't agree. On
Friday, I had to wait for Ward to come to help with homework because I really find it
difficult to get help from Akiko. When I ask her a question, she tells me what she knows
about the subject in general. Then, I ask her what that has to do with the question that's
being asked and she doesn't know. The general information that she is able to give me is
stuff I already know. Ward helps me take that information a step further so that I can
come up with a reasonable answer. But, like I said, sometimes he isn't a lot of help
either. I guess there isn't much to suggest, except to perhaps take that into account when
grading homework - the fact that it can be difficult at times to get homework assistance.
Iwai, Ami
The image of our older TV appeared to be more reddish than that of the
new TV.Is that something to do with physics?
