Office Hours: MW 1:00-1:50, outside of these hours by appointment

 

Lecture: Section 101 MWF 11:00-11:50, Room 101  WSC

                Section 202 MWF 2-2:50, Room 106 WSC (Starts 10/13)

Laboratory: all sections T/R 1:40-2:55, Room 107 WSC

Prerequisite: SCI 105

General:

 

     Physics and music, a strange mixture?  We will examine music and sound from a scientific point of view.  Our discussion will be one of waves and frequencies, as well as notes and scales.  By the end of the class you will think of music in a different way.  You will be familiar with sound waves, propagation of sound, frequency, harmonics, waves on strings and in tubes, effects dues to the listening environment, perception  and synthesis of music.  This is not an intensely mathematical course, but some algebra is required.  We shall encounter logarithms, for example, in our study of loudness.  You should have a calculator capable of calculating logarithms (log, ln) and raising numbers to a power (Yx).  Keep in mind that this is a physics class and we will approach music from a scientific point of view.

 

Grades:

 

            Your Final class grade will be derived from the following percentages

                        Average of 2 Tests (55%)

                        In-class Quiz (15%)

                                Laboratory Experiments (30%)

 

You will not be graded on a “curve”.

 

Electronic Submission of Assignments:  No e-mail with attachments will be accepted.

Students bear sole responsibility for ensuring that papers or assignments submitted electronically to a professor are received in a timely manner and in the electronic format(s) specified by the professor. Students are therefore obliged to have their e-mail client issue a receipt verifying that the document has been received. Students are also strongly advised to retain a copy of the dated submission on a separate disk. Faculty members are encouraged, but not required, to acknowledge receipt of  the assignment

 

 

Tests: Make-up exams will only be given to students with valid excuses as defined by the university handbook (illness, emergency, class trips with prior notification).  The make-up exam may be harder or easier than the regular in-class exam.  Any disputes concerning a test grade must be resolved within one week from the time the tests are returned or from the time the grades are made known to the class.  Any grade disputes after this time limit will not be considered under any circumstances.  Partial credit will be awarded depending how many steps were done correctly in a multi-step problem.  The amount of credit will be at the discretion of the instructor.  No equation sheets are permitted. A list of useful equations and constant will be provided with the test.  This list will be drawn from the important equations found in the chapter.  You should learn all of the important equations and not rely on the equation sheet.

 

Quizzes: There will be a 5-10 minute quiz every week unless interrupted by a test.  This quiz will cover any material discussed in class up to that point of time.  Make-up quizzes are subject to the same conditions as make-up tests.  The Quiz will usually be on Friday.  It may be necessary to change the day and the change will be announced.

 

Final Exam:  The final exam may include any material discussed in class.  Make-up exams will be subject to the same conditions as make-up tests.

 

Honor code: You are bound by the Mercer honor code. The College’s academic misconduct policy will be followed.  All work, for which a grade is received, must be the original work of the student without aid or assistance of another party, or any printed and or electronic data/information. Academic misconduct cases will be referred to the honor council and the student will automatically receive a grade of incomplete (IC) pending a ruling by the honor council. 

 

Cell Phone and Pager Usage: Out of courtesy for all those participating in the learning experience, all cell phones and pagers must be turned off before entering any classroom, lab, or formal academic or performance event

Classroom etiquette: You are expected to conduct yourself as a mature student, respectful of your classmates and instructor.  You may be asked to leave the room if your behavior is disturbing the instructor or your fellow students. Please do not eat in class.  I do not mind if you drink, without drawing attention to yourself. Please do not sleep in class, you will be asked to leave.

Documented Disability Statement:

Students with a documented disability should inform the instructor at the close of the first class meeting.  The instructor will refer you to the office of Student Support Services (SSS) for consultation regarding evaluation, documentation of your disability, and recommendations for accommodation, if needed.  Students will receive from SSS the Faculty Accommodation Form.  On this form SSS will identify reasonable accommodations for this class.  The form must be given to the course instructor for signature and then returned to SSS.

 

To take full advantage of disability services, it is recommended that students contact the Office of Student Support Services, immediately.  The office is located on the third floor of the Connell Student Center.
