IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / â¦ 2). 6 people found this useful. Al Cohen.
2. Experiment: The wavelength and speed of a wave can be influenced by many factors. Adjust the amplitude, frequency, tension, and density as described in the table below. report whether this causes the wavelength and wave speed to increase or decrease.
