Question | Answer |
A series of vibrations you can hear | sound (sonido) |
The part of a sound wave in which molecules are pushed together | compression |
The part of a sound wave in which the molecules are spread out | rarefaction |
Sound waves are a type of wave known as | longitudinal waves |
A moving pattern of high and low pressure that you can hear | sound wave (onda acústica) |
The distance from one compression to the next in a sound wave | wavelength (longitud de onda) |
Loudness of a sound, height of a sound wave | amplitude (amplitud) |
A measure of how high or low a sound is, the steepness of a sound wave | pitch (echada) |
The speed at which a sound wave travels through air in miles per hour | about 768 miles per hour, much slower than light |
A sound reflection | echo (eco) |
A shock wave of compressed sound waves produced by an object moving faster than sound | sonic boom |
Who first broke the sound barrier in an airplane? | Chuck Yegar in 1947 |
What is the relative speed of sound in a solid, gas, liquid - slowest to fastest | Slowest to fastest: gas, liquid, solid |
The number of sound waves per second | Frequency (Frecuencia) |
Why is there no sound in outer space? | There is no matter for sound waves to vibrate |
Absence of all matter - think outer space | Vacuum (vacío) |
A code of long and short sounds (or lights) originally used with a telegraph, no longer in use | Morse Code |
A unit of measure of the loudness of sound (like inches is a unit of measure of length) | Decibel (decibelio) |
