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.
Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Wavelength depends on the medium (for example, vacuum, air, or water) that a wave travels through.Examples of wave-like phenomena are sound waves, light, and water waves.n the case of electromagnetic radiation âsuch as lightâin free space, the phase speed is the speed of light, about 3Ã10 8 m/s. Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3Ã10 8 m/s divided by 10 8 Hz = 3 metres.
