Throughout this unit, internalize the meaning of terms such as period, frequency, and wavelength. Utilize the meaning of these terms to answer conceptual questions; avoid aformula fixation. 1. A wave is introduced into a thin wire held tight at each end. It has an amplitude of 3.8 cm, a...
where f is the frequency measured in cycles per second, or Hertz (Hz), v is the velocity in meters per second, and λ is the wavelength in meters. This means that the amount of wave cycles that pass in a given amount of time depends on how fast the wave is moving and the length ...
The relationship between wavelength and period in confused seas, specified by a two-dimensional wave spectrum, has been investigated numerically for different wave spectra, directional spread parameters, and truncation or cutoff frequencies. The relationship was found to be sensitive to variations in the...
Based on the basic formula quoted above, with one oscillation (i.e., one complete wavelength, from crest to crest) taking five seconds, you get: f=15s=0.2Hz As you can see, frequencies can be less than one per second! For a kid on a swing, moving back and forth from the point w...
Calculate the wavelength , frequency and wave number of a light wave whose time period is3×10−10s. View Solution The equation of progressive wave is given byy=10sin[300π(t−x480)] where x and y are in metre and t is in second. Calculate the amplitude frequency time period and ...
aMeanwhile, although the maximum absorption wavelength related to the transverse resonance of silver nanorods had a few changes, the absorption intensity of the resonance band centered at about 400 nm decreased but the half-width of the resonance band increased obviously within the aging period of ...

A superimposed long period fiber grating design proposed for refractive index sensing is shown to be superior to conventional dual resonance and turnaround point gratings and can operate at any chosen wavelength region by appropriate design. Numerical simulations carried out on standard single mode fiber...
A wavelength-selective coupler constructed with two parallel identical uniform long-period fiber gratings (LPFGs) is analyzed by the coupled-mode theory. T... Kin,Seng,Chiang,... - 《Journal of Lightwave Technology》 被引量: 60发表: 2004年 Analysis of radiation-mode coupling in reflective and...
Learn what the period of a wave is. Discover how to find the period of a wave using the period formula--also called the period equation--based on the frequency of a wave. Related to this QuestionA wave has a speed of 240 m/s and a wavelength of 3.2...
