Rayl
A Rayl, rayl or Rayleigh is one of two units of specific acoustic impedance or, equivalently, characteristic acoustic impedance; one an MKS unit, and the other a CGS unit. These have the same dimensions as momentum per volume. The units are named after John William Strutt, 3rd Baron Rayleigh. They are not to be confused with the rayleigh unit of photon flux, which is used to measure airglow and is named after his son, Robert John Strutt, 4th Baron Rayleigh. Explanation Specific acoustic impedance When sound waves pass through any physical substance the pressure of the waves causes the particles of the substance to move. The sound specific impedance is the ratio between the sound pressure and the particle velocity it produces. ''Specific acoustic impedance'' is defined as: : where \underline, \underline and \underline are the specific acoustic impedance, pressure and particle velocity phasors, \mathbf is the position and \omega is the frequency.

Rayl, California
Rayl (later Hackstaff) is a former town in Lassen County, California. It was located north of Doyle, roughly at the location of present-day Herlong. It was named after David Rayl, who built a hotel/store at the site in 1915. The location was the junction between the Western Pacific Railway and the ill-fated narrow gauge Nevada-California-Oregon Railway (NCO), and Rayl, in addition to constructing the hotel, filed claims for and persuaded the postal service to name the post office after himself, rather than, as preferred by the railroad, Hackstaff (the family name of a relative of the company president). In 1917, Rayl tried to persuade the senators from California to establish a training base at the site, and while the proposal was supported by the surrounding states, it was not accepted. At about the same time, the NCO sold the right-of-way south of the junction to the Western Pacific, which took up the track and relaid it to standard gauge. In the fall of 1920, Rayl leased his ...

Jimmy Rayl
James R. Rayl (June 21, 1941 – January 20, 2019) was an American professional basketball player in the ABA. He was a 6'2" and 175 lb guard. High school career Born in Kokomo, Indiana, Rayl went to Kokomo High School from 1956 to 1959. He was named 1959's Indiana Mr. Basketball and the recipient of the Trester Award for the state of Indiana his senior year. College career Rayl attended Indiana University from 1959 to 1963, where he was an All-American his junior and senior seasons. Rayl averaged 20.6 ppg for his career and still holds the Hoosier single-game scoring record of 56 points, which he did twice against Michigan State and Minnesota. He shot 41.6 percent from the floor and 83.5 percent from the line in 68 games as a Hoosier. Professional career Jimmy Rayl was selected by the Cincinnati Royals in the third round and 23rd pick of the 1963 NBA draft. He later signed and played two seasons for the Indiana Pacers The Indiana Pacers are an American professional ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
