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.
How fast do waves travel? The speed of a wave-its wave speed-is related to its frequency and wavelength, according to this equation: wave speed (metre per second) = frequency (hertz) Ã wavelength (metre). For example, a wave with a frequency of 100Hz and a wavelength of 2m travels at 100 Ã 2 = 200m/s. Check your understanding of the equation by having a go at this activity.
