Sound waves are vibrations being passed on between ... A high pitch sound has a high frequency and makes the air vibrate quickly , so the wave peaks are closer together. A low pitch sound makes ...

Using high-frequency sound waves to make tunable optical filters, modulators and Q-switches is a well-established and convenient technological solution for many applications, reports Neil Savage.

The RMIT University in Melbourne, Australia, has found a way to eradicate such issues. The research project has implemented high-frequency sound waves during the electrolysis process. They prevent the ...

A bioengineer highlights the potential of low-intensity ultrasound for multiple uses, from enhanced drug delivery to the ...

A new study led by UNSW Sydney researchers into a cluster of stars 2700 light years away reveals their stages of evolution ...

The clever bit here is that each individual wave is inaudible on its own, so nobody hears anything unless they're at the ...

This means that, unlike many materials, it operates as a guide for the high-frequency sound waves and lets them more freely interact with the light waves we put into the chip," Dr. Merklein said.

This extra mass slows down the vibrations, creating lower-frequency sound waves that we hear as a lower pitch ... When something vibrates, it pushes and pulls on nearby air molecules, creating areas ...

The relationship between speed, frequency, and wavelength is also established, showcasing sound's predictable behavior in accordance with wave theory. Keywords sound waves, reflection, refraction ...
