36
True or False: The speed of sound is about 343 m/s Answer

37
True Back to JeopardyJeopardy

38
True or False: Sound waves are slower than light waves Answer

39
True Back to JeopardyJeopardy

40
True or False: Sound waves travel faster in outer space than in air. Answer

41
False Sound depends on three things: a vibrating source to create the sound waves, a medium (such as air) to carry the waves, and a receiver to hear them. Sound waves can't travel through a vacuum. Back to JeopardyJeopardy

42
Give the correct order from slowest to fastest for the speed of sound through these three media. [water, air, wood] Answer

43
Some mediums are better at conducting sound than others. Like all gasses, air is a poor medium for sound waves. Liquids, such as water, are better, and rigid, solid substances, such as iron and stone, are even better, while rubber, cork, and cotton are some examples of poor conductors. Back to JeopardyJeopardy (slowest)Air, water, wood (fastest)

44
As you decrease the temperature & pressure of air, does the speed of sound increase or decrease? Answer

45
Decreases! Back to JeopardyJeopardy

46

As the loudness of a sound increases, the amplitude of the wave ______________ Answer

49
increases Back to JeopardyJeopardy

50
The frequency increases when the source and the observer approach each other and decreases when they move apart. Answer

51
