Jennifer Rios Negative Effects of Noise Pollution Technological progress has brought humanity numerous benefits. All types of devices and gadgets allow people to save time‚ work more efficiently and stay in touch with the rest of the world. However‚ there is also a flip side. Growing industry‚ an increasing number of vehicles and constant information overload causes a significant and underestimated problem – noise pollution. The term‚ noise pollution‚ is used to define unwanted sounds that are

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher

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

Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

Research Question: E. coli strain MM294 is placed under different sound frequencies. Does sound frequency affect the growth of E. coli strain MM294? Background: Noise pollution is a problem in urban areas and can be the cause of several health issues and increase risks of disease. It is interesting that even something inanimate like sound could affect so much of biological processes. The movement of energy through matter produces sound. Sound is a mechanical wave that travels
