Sinusoidal waves
This is a solution of the wave equation. Holding either x or t fixed results in a sinusoidal disturbance, so the wave is periodic in both space and time.. Let us now examine the spatial period. The spatial period is known as the wavelength and is denoted by .An increase or decrease in x by the amount leaves u unaltered; that is,

Wave frequency is a fundamental concept when dealing with sinusoidal waves. Frequency, denoted by the symbol ( f ), refers to the number of cycles a wave completes in one second and is measured in Hertz (Hz). For example, in our exercise, the wave frequency is given as (500 text{ Hz}). This means that every second, the wave completes 500 ...

Early studies of temperature-dependent rock mechanics are focused on the static or quasi-static loading, where the P-wave velocity, thermal conductivity, strength, and elastic modulus of rocks gradually decrease with increasing temperature, while the peak strain and porosity increases (Qin et al., 2020; Zhu et al., 2023).With the split Hopkinson pressure bar …

1.2: Sine Waves
So far we have only considered a sine wave as it appears at a particular time. All interesting waves move with time. The movement of a sine wave to the right a distance d may be accounted for by replacing x in the above formula by (x - d). If this movement occurs in time (t), then the wave moves at velocity (c = d∕t).

Sinusoidal waves can be used to model various physical phenomena, including electromagnetic radiation, sound waves, and the motion of vibrating objects. The propagation of sinusoidal waves can be affected by the properties of the medium, such as the speed of light in a vacuum or the speed of sound in air, which determine the wave's velocity. ...
