This problem has been solved! Therefore, if the oscillation amplitude is doubled while m and k are unchanged then the period will remain 2.0s. The amplitude of any wave that depends on the media it travels helps measure the energy amount carried by that wave during propagation. This speed is the speed of a wave. Why does the speed decrease when a ray of light travels from rarer to denser medium? The speed remained a near constant value of approximately 16.2 m/s. The small variations in the values for the speed were the result of experimental error, rather than a demonstration of some physical law. The factors which change the nature of amplitude of a wave are. Wave: In physics, a wave is considered an energy transport phenomenon that transmits energy along with a medium without carrying any matter. As waves travel into the denser medium, they slow down and wavelength decreases.

Sometimes a wave encounters the end of a medium and the presence of a different medium. The difference between frequency and amplitude is that: frequency is a measurement of cycles per second, and amplitude is a measurement of how large a wave is. When the amplitude increases in a wave, it carries more energy and gains higher intensity; in terms of sound waves, if the intensity is high, then the quality of sound will be loud. Why does wavelength affect speed? In fact, the speed of a wave is not dependent upon (causally affected by) properties of the wave itself.
