amplitude (the height of the wave, corresponding to loudness), frequency (the number of waves passing a point per second, related to pitch), time period (the time it takes for one complete wave cycle to occur), and velocity (the speed at which the wave travels...
What is sound? Robert Boyle's classic experiment How sound travels The science of sound waves Whispering galleries and amphitheaters Measuring waves Understanding amplitude and frequency The speed of sound How to measure the speed of sound Sound in practice Find out more What...
The aim of the present study is to provide insight on the induced compressive perturbations together with the modifications of the environmental parameters in the course of Alfvén wave interaction with a solar magnetic null-point. The shock-capturing Go
A microstrip antenna for spin-wave excitation is placed in front of the bended section of the waveguide. A radio-frenquency field in the form of hac(t) 5 H0?sin(2pft), with the field amplitude H0 ranging from 5 to 100 Oe and the frequency f in the gigahertz range, is supplied to ...
A wave source recedes from you at 11.0 m/s, and the wavelength you measure is 22% greater than what you would measure if the source were at rest. What is the wave speed? A point source is generating circular water waves. (a) What does the amplitude of the...
What does wave speed measure?How fast are pressure waves?Wave speed depends on frequency and what else?How and why does water depth affect wave velocity, in water waves? What is the "somewhat simple" version of the physics involved in this (regarding frequency, amplitude, wavelength, etc.)?
Increasing the amplitude of the wave causes the sound to be louder, but it doesn't affect the shape of the waveform or cause it to be much more physically powerful. However, extremely intense sounds — like sounds that are physically painful to human ears — are usually nonlinear. They can...

The use of speech as a digital biomarker to detect stress levels is increasingly gaining attention. Yet, heterogeneous effects of stress on specific acoustic speech features have been observed, possibly due to previous studies’ use of different stress l
Secondary waves are a type of shear wave in seismology and are often compared to primary waves which are also generated simultaneously by an earthquake. Secondary waves move more slowly than primary waves, but have higher amplitude and are more destructive, and move with a shear force that ...
