resonance   1. Sonometer

 

In this experiment you will be observing the oscillations of a string. The arrangement of the equipment is similar to a guitar. You will be plucking the string and observing the frequencies using a FFT.

resonance   2. Resonance Tube

 

This experiment investigates standing sound waves in a tube subject to different boundary conditions. One end of the tube is closed off with a small speaker. The other end is closed with a movable piston which can be used to change the length of the tube. Sinusoidal sound waves are produced by the speaker and detected by a small microphone in the tube. At resonant frequencies of the tube, the sound waves will be enhanced. In a second experiment, a pulse of sound is sent down the tube and then the reflected pulse is examined.

equilibrium of a particle   3.Electrostatics

To study charges, the forces they exert on each other, and their flow between materials, both conducting and non-conducting. Many of these tests are similar to ones carried out in the eighteenth century. Most of the observations in this experiment will be qualitative.

work-energy   5. Oscilloscope and EKG sensor

In this lab, the students become familiar with 2 oscilloscopes and EKG sensor. The oscilloscope that you will be using is made by BK Precision. You will also become familiar on the use of the Capstone scope and you will use the EKG sensor in conjunction with the Capstone scope.

newton's 2nd   6, 7. Voltage, Current, and Resistance (Parts I and II)

The purpose of this experiment is to learn how voltage and currents are generated and measured in the laboratory, and to investigate how voltage and current are related in resistors. This lab will be completed in two classes.

collision 1D   8. Current Balance

In this experiment, the students verify that the force between two wires are proportional to the product of the currents, and estimate the proportionality constant involved.

conservation of energy   9. Charge to Mass Ratio of Electron

In this experiment e/m of the electron is determined from the relationship between the electric potential used to accelerate the electron to a given speed, the strength of the magnetic field that influences the electron's motion, and the radius of the circular path which the electron follows.

centripetal force   10. Electromagnetic Induction

In this experiment an emf will be induced in one coil by moving a magnet near the coil. Also, by moving a second coil with a current in it near the first coil, and by changing the current in the second coil.

  11. Snell's Law

In this experiment students examine Snells law. They will shine a laser through various materials and determine the amount of diffraction that occurs.

eye   12. The Human Eye

In this experiment, students will learn about lenses and their properties by working with a model of the human eye. Astigmatism, near, and far sightedness are discussed.
