Seismic Waves What are seismic waves? Seismic waves are the waves of energy caused by breaking of rock within the earth or an explosion. These waves are the energy that travels through the earth and is recorded on seismographs. There are many different types of these waves‚ but the two main ones are the body waves that usually travel though in inner layer of the earth‚ and the surface waves that only move around the surface of the planet. Body waves travel through the inner layer of the earth

not everything. There is also the sound film.” Thus explained the French filmmaker René Clair in 1929. With this statement Clair was challenging us all to push the boundaries of sound design in films. From the primitive synchronization experiments of Lee de Forest and Thomas Edison to state-of-the-art Dolby Digital 10.2 surround sound‚ there are no boundaries for creating a virtual deluge of sound. Even though one is tempted to hypothesize about the future of sound design‚ it is only through an educated

SHOULD WE USE ELECTROMAGNETIC WAVES FOR MEDICAL PURPOSES? In terms of definition‚ Electromagnetic Wave is a “non-particulate radiation (radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge)”. Thus‚ in simpler words‚ electromagnetic is a transmission of energy‚ caused by the oscillation and of electric and magnetic fields. The word electromagnetic wave or electromagnetic radiation may sound complex. However‚ without

Alpha waves are regular‚ have medium frequency‚ and occur while resting. Beta waves are irregular‚ have a low amplitude‚ and occur while attentive. In stage one of the sleep cycle‚ we experience Theta waves‚ which have similar frequencies and regularity to Alpha waves. Stage two also involves Theta waves‚ but may also have short bursts of Alpha and Beta waves called sleep spindles‚ or Delta waves called k complexes. These are the two shallowest sleep

Experiment 7: Velocity of Sound Laboratory Report Hazel Guerrero‚ Kyle Iddoba‚ Matthew Jocson‚ Thea Lagman Department of Biological Sciences College of Science‚ University of Santo Tomas Espanya‚ Manila Philippines Abstract Verification of the relationship between frequency of sound and its wavelength and the determination of the velocity and the speed of sound in different mediums was the main focus of this experiment. The speed of sound and its velocity was determined using the resonance

Sweet Caroline at Fenway The sky is pitch black‚ but bright lights illuminate the stadium. The perfectly mowed Kentucky Blue Grass is a mixture of shades of vibrant green colors. A raised‚ firmly packed pile of light brown dirt sits in the middle of the infield. Straight in front of this mound is home plate. First‚ second‚ and third base sit in their respective places around the infield as well. Two white lines go down the sides of the field in order to tell if a ball is foul or fair. Advertisements

Sound and acoustics It is common to think that acoustics is the study of music. Although acoustics does comprise the study of musical instruments‚ it also includes an extensive range of topics‚ including: SONAR systems‚ noise control‚ ultrasounds for medical imaging and other processes‚ electroacoustic communication‚ seismology‚ etc. [1] In general‚ acoustics is the study of mechanical waves including sound‚ vibration‚ infrasound and ultrasound. When talking about the acoustics‚ it is essential
