4 WHAT IS SOUND? Sound is a form of energy that can be heard and travels in waves. When matter vibrates or moves back and forth very quickly, a sound is made. Sound waves can travel through...
5 Μαΐ 2017 · Sound waves are longitudinal mechanical waves that require a medium such as air or water to propagate. There are two types of mechanical waves: longitudinal waves where particles of the medium move parallel to the wave direction, and transverse waves where particles move perpendicular.
18 Μαρ 2012 · Properties of sound waves include frequency, wavelength, amplitude, and pitch. The speed of sound depends on the medium and temperature, being fastest in solids and slowest in gases. Reflection and refraction of sound waves results in phenomena like echoes and resonance.
