Lab 1: Damped, Driven Harmonic Oscillator
1 Introduction
The purpose of this experiment is to study the resonant properties of a driven, damped harmonic
oscillator. This type of motion is characteristic of many physical phenomena.

Vibrations and Waves MP205, Assignment 4 Solutions
1. Find the frequency of vibration under adiabatic conditions of a column
of gas confined to a cylindrical tube, closed at one end, with a well-fitting
but freely moving piston of mass m.
From the diagram
Vibrations and Waves MP205, Assignment 1 Solutions
1. Consider a vector z defined by the equation z = z1 z2 , where z1 = a + ib,
z2 = c + id.
(a) Show that the length of z is the product of the lengths of z1 and z2 .
(b) Show that the angle between z and
Vibrations and Waves MP205, Assignment 3 Solutions
1. Two vibrations at right angles to one another are described by the equations
x = 10 cos(t)
y = 5 cos(2t + /4)
Construct the Lissajous figure of the combined motion.
So we have Ax = 10 and Ay = 5. Phase
Vibrations and Waves MP205, Assignment 2 Solutions
1. Express the following in the form Re[Aei(t+) ]
(a) z = sin t + cos t.
(b) z = cos(t /3) cos t.
(c) z = 2 sin t + 3 cos t.
(d) z = sin t 2 cos(t /4) + cos t.
Firstly recall that sin() = cos( /2) and cos
Physics 300 Midterm Exam
1. (20 points) Consider a guitar string with length L=60 cm, mass M=0.20 g under tension T=50 N. As we saw in
class, plucking the string results in the fundamental and many harmonics. What is the frequency of the lowest
mode (the
Physics 300 Final Exam
1. (15 points) You are given polarizers, a half and quarter wave plate and the task of building a
device that can attenuate the intensity of a polarized light source by an adjustable amount (from
zero all the way to the input intens
