Wave Homework Don’t do your work on this sheet!! Vsound=345m/s. 1. A regular wave train has a wavelength of 10.5mm. If the wave is moving at 34.78m/s what are the wavelength‚ frequency‚ period and velocity in the proper units? 2. How are frequency and period are related? 3. A wave generator produces 16.0 pulses in 4.00 seconds. What is the period? 4. What is the frequency for the problem above? 5. If a water wave has 10.0 meters between crests and have a frequency

Longitudinal and transverse waves Sound is transmitted through gases‚ plasma‚ and liquids as longitudinal waves‚ also called compression waves. Through solids‚ however‚ it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure‚ causing local regions of compression and rarefaction‚ while transverse waves are waves of alternating shear stress at right angle to the direction of propagation

Nijee Warfield Professor Rettura Survey to American Literature Nijee Warfield 11/22/13 Professor Returra Final Paper The Sound and the Fury The Sound and The Fury is unique and strange novel. Each of the chapter or parts are written from a first person view. Its context is written from four different prospective‚ that of the three Compson brothers and one through Faulkner’s own eyes‚ but he seems to focus on Dilsey‚ the Compson’s cook. Dilsey takes a great part in raising the

THE FRENCH NEW WAVE LA NOUVELLE VAUGE During the German occupation French cinema thrived‚ this was due to the protection given to it from foreign competition. When the war ended American films flooded into the French market‚ these films were greeted with great enthusiasm‚ as many were curious about all aspects of American culture. The Blums-Byrnes Agreement regulated the flow of foreign films in the French market. This agreement stated that French films could only be shown for 13 weeks

What are UltraSonic Waves? Ultrasonic waves are sound waves with frequencies high about human hearing and short wave lengths. Sound waves have frequencies about 20‚000 to 100‚000. Also Ultrasound frequencies range from 20 kHz (the upper range of hearing for a young adult human) through 150 kHz (audible to some bats and other creatures)‚ right up to 10 MHz (used in some medical treatments and industrial cleaning applications). While these frequencies overlap with those of radio waves‚ they are different

Safe and Sound Take a minute to think about one thing from your childhood you still have an endless love for. How does it make you feel? Happy? Joyful? Safe? For Holden Caulfield‚ the exhibits in the Natural History museum are what make him feel safe. The museum scene in The Catcher in the Rye by J.D. Salinger‚ shows how someone changes throughout life‚ but memories remain the same and stick with us forever. There are some things in life that change‚ like our hair or clothes‚ and other things

Radio waves and Microwaves Radio communications Radio waves are used to broadcast radio or television signals from transmitters‚ which are then converted into electrical signals with an aerial (which is made out of metal to absorb the radio waves) so you can hear and see them. When done so the aerial converts this wave into an electrical signal (because of the electromagnetic waves energy exciting particles in the aerial and causing them to oscillate/vibrate and thus create an electrical current)

A Sound of Thunder‚ Part 1 Ray Bradbury The sign on the wall seemed to quaver under a film of sliding warm water. Eckels felt his eyelids blink over his stare‚ and the sign burned in this momentary darkness: TIME SAFARI‚ INC. SAFARIS TO ANY YEAR IN THE PAST. YOU NAME THE ANIMAL. WE TAKE YOU THERE. YOU SHOOT IT. Warm phlegm gathered in Eckels’ throat; he swallowed and pushed it down. The muscles around his mouth formed a smile as he put his hand slowly out upon the air‚ and in that

Radio waves for Communication Radio waves are electromagnetic waves with wavelengths larger than the infrared light. Like all other electromagnetic waves‚ they travel at the speed of light. The wavelengths can vary from the size of a football field to the size of a football. They can be produced naturally by large stars and by lightning. Man-made radio waves are used for transmitting signals and currents. Specific Properties of Radio Frequency (RF) Current Radio frequency is the frequency of radio
