Sound waves Science project

Sound waves (frequency)

The frequency of sound that is perceptible to humans ears is 20-20,000 Hz. In air at standerd temperature and preusser, the corresponding wavelength of sound waves range from 17m to 17mm.

Sound waves (amplitude)

Amplitude is the highest point of a wave from its resting position. Which sound waves, it is the extent to which air particles are displaced and this amplitude of a sound or sound amplitude is experienced as the loudest of the sound.

Sound waves (velocity)

Velocity for Sound waves

Sound waves (wavelength)

For soundwaves in air the speed of sound is 343 m/s . The wavelength of sound frequencies audible for humans to hear is about 20 Hz 

Sound waves (through things)

Sound waves through air and sound move similar. Sound waves can travel through any substance including gases, liquids, and solids. Sound waves do not exist if it doesn't have something to travel through, that's why sound does not exist in outer space. Glass is a type of hard material that doesn't have a buffer against a vibration. It will let sound effect itself much more than other materials would. That's what sound waves does to glass

Sound waves (random facts)

Sound waves happen by vibration of an object. Sound waves travel through air like water waves travel through water. Objects that you sound waves are peoples vocal cords and a telephone ring etc.
