1. A sound wave is different than a light wave in that a sound wave isa. produced by an oscillating object and a light wave is not.b. not capable of traveling through a vacuum.c. not capable of diffracting and a light wave is.d. capable of existing with a variety of frequencies and a light wave has a single frequency.Answer:BSound is a mechanical wave and cannot travel through a vacuum. Light is an electromagnetic wave and can travel through the vacuum of outer space.2.. Two musical notes that have a frequency ratio of 2:1 are said to be separated by an octave. A musical note that is separated by an octave from middle C (256 Hz) has a frequency of _____.a. 128 Hzb. 254 Hzc. 258 Hzd. 345 Hze. none of theseAnswer:ATwo notesseparated by an octavehave a frequency ration of 2:1. If a note is one octave below 256 Hz, then it must have one-half the frequency.1. A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sounda. is more dense than air and thus has more inertia, causing the bunching up of sound.b. waves have a speed that is dependent only upon the properties of the medium.c. is like all waves; it is able to bend into the regions of space behind obstacles.d. is able to reflect off fixed ends and interfere with incident wavese. vibrates longitudinally; the longitudinal movement of air
