organ will have multiple sets of pipes called stops. Organs can have as little as 12 pipes to as many as 20‚000. Introduction All wind instruments rely on the vibration of air to produce sound. They all have some sort of pipe or tube in which standing air resonates and produces a fundamental frequency. This frequency of the sound produced is dependent on the length of the tube. In some instruments‚ the length of the tube can be modified to alter the frequency produced. However‚ this is impractical

ambulance it seems to take forever for it to come around you? Or how about times when you yell “HEY YOU” or “MOM” in a grocery store standing in the middle of the aisle people from all directions can hear you….and some even answer? Or lastly how about this example‚ have you ever seen an insect in the water kicking and it seems if the ripple is getting bigger and bigger and the waves are going in all directions not just straight back? If so‚ then you’ve experienced The Doppler Effect. The Doppler Effect

Young’s double slits Formal Lab Florencia Shi Purpose: The double slits experiment was conducted to observe the interference of light waves‚ to explore how interference pattern would be affected by different colours‚ and to determine whether interference would change if the angle of slits was changed horizontally or vertically. Hypothesis: Dark and light bands would be seen‚ and red light causes wider nodal spacing‚ while blue light causes shorter nodal spacing. Materials: In this experiment

intensity occurs thus proving the resonance phenomenon. The length of the water column must be changed by either lowering or raising the level of water while holding the tuning fork over the open end of the tube. Overall‚ the lab proved that the standing wave phenomenon in a column of air (resonance) occurs when the length of the column is λ/4‚ 3λ/4‚ 5λ

Physics notes – Interactions of light and matter Young was able to explain this result as a wave-interference phenomenon – the double-slit interference pattern demonstrates the wave-like nature of light. Free download and print from www.itute.com ©Copyright 2009 itute.com Explaining the interference pattern using the wave model Light has been described both as a particle and as a wave. Isaac Newton (~1665) made up a particle model of light to explain many of the known behaviours

How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? 2.

A microphone located at the opposite end of the rail detects two pulses of sound‚ one that travels through the air and a longitudinal wave that travels through

Review Waves‚ Sound and Light Waves- What are Waves? 1. 1 .The substance that a move through is called a medium. 2. True or False: Particles are squeezed together during rarefactions. 3. True or False: Waves that require a medium through which to travel are called electromagnetic waves. 4. True or False: The matter in the medium moves perpendicular to a transverse wave. 5. What medium is often used to transfer computer information? Optic Fibers 6. 6 .A sound wave is made

artists is the noise barrier that they use to reflect or absorb the sound waves. Different barriers cause different effects on the sound waves. There are five different and sound barriers that can alter the behavior of the sound wave: absorption‚ reflection‚ noise cancelation‚ room within a room‚ and diffusion. Absorption is caused by a soft surface being struck by the sound wave. The ability of an object absorbing the sound wave is based on five different factors: Cell size‚ Tortuosity‚ Porosity
