1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving then when the sound gets closer‚ the volume will increase and when the sound passes by you‚ the volume will start decreasing. 2.

have contributed to theories involving light. Of these‚ the wave-particle duality is arguably the most strange and noteworthy concept in the field. Throughout history‚ some physicists have argued that light behaves as a wave‚ such as Christiaan Huygens and others‚ such as Isaac Newton have proposed that light consists of particles (Wave-Particle Duality‚ March 2010). Today‚ as stated in the wave-particle duality‚ light is said to exhibit wave-like and particle-like properties. And still today‚ physicists

use of recorded sound in films was a technological achievement that would dramatically change the way audiences experience cinema. The transition from silent cinema affected many studios and filmmakers‚ who had to adapt to the new technology to prevent their careers from fading into obscurity. One filmmaker who was able to adapt to the changing industry was director Fritz Lang. The Austrian born director‚ whose career began in post-war Germany in 1919‚ made the transition to sound in 1931 with the

the friction of the jagged edges of the fault and it unsticks‚ all that stored up energy is released. The energy radiates outward from the fault in all directions in the form of seismic waves like ripples on a pond but much more violent. The seismic waves shake the earth as they move through it‚ and when the waves reach the earth’s surface‚ they shake the ground and anything on it‚ like our houses and workplaces. The tool that scientists use to record and measure earthquakes is called

Speed of Sound in Air By: James Chen Lab Partner: Jin Zhang and Jake Salpeter Phys 130‚ Lab section: EE11 TA: Khaled Elshamouty Date of lab: October 29‚ 2013 Introduction Sound is a longitudinal (compressional) wave caused by a vibrating source. In this experiment‚ we use standing sound waves created by the tuning forks to determine the speed of sound in air in a tube when it reaches different resonances. In this lab we focused primarily on using standing sound waves (compressional
