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.
That means that 5 x 1014 wave peaks pass a given point every second. Light has a constant speed through a given substance. For example, it always travels at a speed of approximately 3 x 108 metres per second in a vacuum. This is actually the speed that all electromagnetic radiation travels - not just visible light. There is a simple relationship between the wavelength and frequency of a particular colour of light and the speed of light:
