Physics 124, Lab Section D54
TA: Kyle Reid
Date of Lab: November 6, 2013
Introduction:
This lab is designed to measure the true angular velocity of the Sun, along with the period of
rotation using the observation of sunsp
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,
