The higher the objects temperature, the faster the molecules will vibrate and the shorter the wavelength will be. As the wavelength decreases, the energy increases. Equivalently, the longer the photons wavelength, the lower its energy. As wavelength increases, how is wave period affected? b. Where does the term bum a cigarette come from? For this reason, the wavelength ratio is the inverse of the frequency ratio. What wavelengths longer or shorter do higher temperature and lower temperature correspond to? Mechanical and electromagnetic waves with long wavelengths contain less energy than waves with short wavelengths. What happens to that energy? What type of electrical charge does a proton have?

Share Cite Improve this answer Follow answered Mar 22, 2017 at 11:41 Jakob 274 1 8 The relationship between wavelength and frequency is called an inverse relationship, because as the frequency increases, the wavelength decreases. The correct answer is d. Wavelength decreases. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. Since the dispersion relation of water waves is such that longer wavelength waves propagate faster, you have your answer. So the longer the wavelengths and lower the frequency results in lower energy. Electromagnetic waves can travel through a medium or a vacuum.
