Answer 1

Ditto doug's comment--I don't mind helping with a hw problem or helping to clarify a concept if you have a question, but just doing all your hw is too much.

Multiple choice is already too easy without getting someone else to do it for you.

Answer 2

1) Shorter wavelengths change direction (refract) more than longer ones.
2) Waves travel at c, the speed of light, therefore is wavelengths are longer, there will be fewer of them passing a given point each second, so the frequency will be lower. Larger wavelength = smaller frequency.
3) In quantum mechanics, everything has a wavelength. What MAKES it quantum mechanics is the fact that electron energies in the atom are quantized.
4) Higher frequency (lower wavelength) = higher energy.
5) The principal quantum # corresponds to the electron shell #. In shell #2, how many electrons does it take to fill it? (HINT: look at a periodic table).

Answer 3

1. (C) It's a characteristic called 'dispersion'.

And if you think I'm gonna waste *my* time doing *your* homework, re-think it.

You need to actually *read* and *study* your textbook.

You only get to learn this stuff once. And I had my turn 40+ years ago ☺

Answer 4

The chapter that the questions are at the end of will have the answers you seek. Read it!
