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.
Best Answer: If you increase frequency you decrease wavelength. They are inversely proportional. Lower wavelength means higher energy. If you increase frequency you increase energy. That's why short wavelength x-rays are bad for you (lots of energy to damage DNA) but long wavelength radio waves aren't.
