Vibrations and Waves

As taught in: Fall 2004

This is a picture of Prof. Lewin, taken by Prof. Lewin. It was the "Astronomy Picture of the Day" (APOD) on September 13, 2004. It was also presented to his 8.03 students as a challenge to obtain extra course credit if they were able to explain this phenomenon. On December 7, Prof. Lewin revealed the physics (and demonstrated it) in lecture 22. The solution was also revealed by APOD to the many thousands of people who were puzzled by it and who tried to explain it.

Course Features

Course Description

In addition to the traditional topics of mechanical vibrations and waves, coupled oscillators, and electro-magnetic radiation, students will also learn about musical instruments, red sunsets, glories, coronae, rainbows, haloes, X-ray binaries, neutron stars, black holes and big-bang cosmology.

OpenCourseWare presents another version of 8.03 that features a full set of lecture notes and take-home experiments.

OpenCourseWare also presents Professor Lewin's freshman physics course series 8.01 – Newtonian Mechanics - with a complete set of 35 video lectures from the Fall of 1999 and 8.02 - Electricity and Magnetism - with a complete set of 36 video lectures from the Spring of 2002.

Lectures - Homework - Solutions - Mini-Quizzes - Exams

There will be 23 lectures, 11 problem sets, 10 mini-quizzes, 2 exams during regular lecture hours, and a 3-hour final. During exams, you are expected to know all material covered in (i) the lectures, (ii) the reading assignments, (iii) the problem sets and (iv) recitations. Please hand in your homework on the due dates; solutions will be made available on the website later that day.

E1 (after L10) Exam 1
E2 (after L19) Exam 2
E3 (after L23) Final Exam

There will be no make-up exams!


Every Tuesday, during a 5-minute break in the lectures, we will have a simple mini-quiz. Some courses give mini-quizzes in recitations. Instead of breaking up the 50-minute recitations, it may be advantageous to do it during a pause in the 85-minute lectures.

Missed Work

A missed homework, quiz or exam counts as a zero. Only in case of verifiable illness can you be excused.

Course Grade

Mini-Quizzes 5%
Homework 15%
Participation in Recitations 5%
Exam 1 15%
Exam 2 20%
Final exam 40%

Take-Home Experiments

There will be a handful of take-home experiments which are part of the problem sets. To do them, you will need an 8.03 experiment kit. The kits will have to be returned at the end of the term.
