Question

From the following statements, identity all those that are TRUE. a. When a sound wave is said to be intense, it means that the particles are vibrating back and forth at a high frequency. b. Intense sounds are usually perceived as loud sounds. c. The ability of an observer to hear a sound wave depends solely upon the intensity of the sound wave. d. Two sounds which have a ratio of decibel ratings equal to 2.0. This means that the second sound is twice as intense as the first sound. e. Sound A is 20 times more intense than sound B. So if Sound B is rated at 30 dB, then sound A is rated at 50 dB. f. A more rigid material such as steel has a higher elasticity and therefore sound tends to move through it at high speeds. g. A loud shout will move faster through air than a faint whisper. h. Sound waves would travel faster on a warm day than a cool day. i. A shout in a canyon produces an echo off a cliff located 127 m away. If the echo is heard 0.720 seconds after the shout, then the speed of sound through the canyon is 176 m/s. j. Ultrasound waves are those sound waves with frequencies less than 20 Hz. k. When a standing wave pattern is established, there are portions of the medium which are not disturbed. l. A standing wave is really not a wave at all;it is a pattern resulting from the interference of two or more waves which are traveling through the same medium. m. The fundamental frequency of a guitar string is the highest frequency at which the string vibrates. n. The fundamental frequency of a guitar string corresponds to the standing wave pattern in which there is a complete wavelength within the length of the string.
