Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy

Author: Haoyang Chen Date: 2/23/2013 Experiment No.: 2 Title: Synthesis - A Square Wave‚ a Musical Note and Sound Cancellation Introduction: In this experiment‚ we will do three parts to find out the synthesis sound. They are a Square Wave‚ a Musical Note and Sound Cancellation. For the first part‚ it is the superposition of sine wave. We are going to construct a square wave (approximately) by adding together some pure tones of different frequencies. This stretched string vibrating at
