true or false. If the power of a wave is halved, the intensity is reduced to
onefourth its original value. - correct-answer-false. power is proportional to
intensity. if power is halved, intensity is halved
true or false. propagation speed increases as frequency increases - correctanswer-
false. propagation speed is determined by the medium only

Medium 1 has a density of 9 and a stiffness of 6. medium 2 has a density of 8 and
a stiffness of 6. Which medium will sound travel slower - correct-answer-Medium
1. greater density= lower speed
True or False A wave with a frequency of 15,000 MHz is ultrasonic -
correctanswer-True. Ultrasound is greater than 20,000 hz
True or false. if the amplitude of a wave is increased to 3 times the original value,
the intensity is increased by 6 times. - correct-answer-False. intensity is
proportional to amplitude squared.
Which of the following characteristics will create the fastest speed of sound.
a. high density, high stiffness
b. low density, high stiffness
c. high density, low stiffness
d. low density, low stiffness - correct-answer-b. low density, high stiffness. speed
is inversely proportional to density and directly proportional to stiffness.
