Stan and Anna are conducting a slinky experiment. They are studying the possible effect of several variables upon the speed of a wave in a slinky.
Their data table is shown below. Fill in the blanks in the table, analyze the data, and answer the following questions. See Speed Values Multiply the frequency by the wavelength to determine the speed. In rows 1 and 2, the wavelength was altered but the speed remained the same. The same can be said about rows 3 and 4 and rows 5 and 6. The speed of a wave is not affected by the wavelength of the wave. In rows 1 and 2, the wavelength was increased and the frequency was decreased.
Wavelength and frequency are inversely proportional to each other. Whenever the medium is the same, the speed of the wave is the same. However, when the medium changes, the speed changes. The speed of these waves were dependent upon the properties of the medium.
The above example illustrates how to use the wave equation to solve mathematical problems. It also illustrates the principle that wave speed is dependent upon medium properties and independent of wave properties.
Even though the wave speed is calculated by multiplying wavelength by frequency, an alteration in wavelength does not affect wave speed. Rather, an alteration in wavelength affects the frequency in an inverse manner. A doubling of the wavelength results in a halving of the frequency; yet the wave speed is not changed.
Two waves on identical strings have frequencies in a ratio of 2 to 1. If their wave speeds are the same, then how do their wavelengths compare? Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Use a photometer to measure the energy of a wave.
Convert the energy into joules J. What is wavelength measured in? How do you calculate energy from wavelength? Convert your wavelength into meters. This gives you the wave's frequency. The result is the waves energy in joules J. How do you calculate wavelength from wavenumber? Take your wavenumber, noting the units. Divide 1 by the wavenumber. Preset optional. Wave velocity.
