Introduction:
This lab is designed to investigate the wavelength and frequency of different sound waves
through the use of an oscilloscope; more specifically, the wavelength and frequency of a tuning
fork, and your voice. Wavelength is the spatial period
Introduction:
This lab is designed to investigate diffraction, and diffraction patterns. In this lab, you will
measure the width of your hair with the help of a laser, ruler, and screen. You will use the laser
to diffract light with a piece of your hair,
Introduction
Galileo was a scientist who performed many quantitative experiments regarding
many topics, one of which is the ball and ramp experiment. In this lab, an
experiment was performed to determine the acceleration due to gravity, g. A ball
