The magnitude of an earthquake is thus represented by a single, instrumentally determined value. Pitch (frequency) - shown by the spacing of the waves displayed. Amplitude is the energy of the wave measured from the rest position to the top of the crest. Both Wave C and Wave D travel at the same speed. It also does not affect wave speed. To achieve a higher amplitude or maximum displacement, more energy must be applied or more work must be performed. Amplitude and wavelength are not directly proportional, as amplitude is a part of wavelength. The speed of a wave is only altered by alterations in the properties of the medium through which it travels. The change in the amplitude of ocean waves is caused by the slowing of the wave speed. Why does seismic wave velocity increase with depth? The amplitude of a wave doesnt affect the amplitude because Pressing the finger at different places changes the length of string, which changes the wavelength of standing wave, affecting the frequency. The energy transported by a wave is directly proportional to the square of the amplitude. When we study a simple harmonic motion, we can see that the amplitude of the simple harmonic wave decreases exponentially over time. Larger the amplitude, the higher the energy. These media are distinguished by their properties - the material they are made of and the physical properties of that material such as the density, the temperature, the elasticity, etc. We can deduce from the energy and amplitude of wave relationships that if the energy of a wave is large, its amplitude will be high. If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s. For a high amplitude to occur, the length of the amplitude must be to its maximum, creating a long path to help the wave carry more energy and transfer more particles that will lead to more propagation in the medium and help increase the amplitude. If the medium does not change as a wave travels, the wave speed is . It also does not affect wave speed. The amplitude will make a difference in the speed.

Two identical traveling waves, moving in the same direction, are out of phase by \frac {\pi} {3} rad. The angular frequency, , is 2 times the frequency: = 2f. If you try to increase the loudness of the system, this loudness will occur due to the increase in amplitude length, which leads to a louder voice or sound. On the other hand, if the crest of the ocean wave . The second assumption says that the current speed V is small compared to the wave propagation speed, C = /k, where is the wave frequency; this implies a time scale separation between faster waves and slower currents and thus enables wave averaging for the current dynamics.
