As a student, who knows herself to be a little slow but who is nonetheless tenacious, I was rather hurt by your response. So I went and looked up a couple of physics textbooks for myself. What I found was much more like what Integral and Hurkyl briefly mentioned than your definition.
So I would like, respectfully and humbly, to ask you again - please tell me the name of a physics textbook which provides a definition of a wave like the one you gave, and explains sound and light (or electromagnetic waves in general) in terms of the words in your definition.
Regarding the 'idiot' term: I spoke with my Chemistry teacher about this, and she got quite angry. First, she said that there's no evidence in pedagogical theory (or practice) that gratuitous insults do anything but harm a student's ability to learn. Second, she said that a teacher should *always* encourage her students to ask questions about something they don't understand, work independently, and foster their curiosity. Third, she said that our school has a clear policy about language "Any foul or hostile language used in class will not be tolerated. This includes any derogatory statements and profanity. Direct or indirect personal attacks are strictly not permitted. Insults and negative attitudes are not allowed.[/color]" She encouraged me to go back to you and ask my questions again, and said that if you continue to break the school's policies, she will report you to the Head Teacher.
