Unformatted text preview: 5. If the waves become longer, what happens to frequency <25.4>? This relationship should make sense if you imagine the graphs of the waves. 6. If the velocity of a sound wave varied with frequency, how would this affect your experience of going to see the symphony <25.4>? Wave Speed Examples: 7. A sound wave with frequency 262 Hz has a wavelength of 1.29m. What is the velocity of the sound wave? s / m 338 ) Hz 262 )( m 29 . 1 ( f v = = = 8. If another sound wave, traveling at the same velocity, has a longer period (0.007 s), what is its wavelength? T v = s 007 . s / m 338 = m 37 . 2 ) s 007 . )( s / m 338 ( = = 9. If the crest of an ocean wave moves a distance of 20 m in 5 seconds, what is the speed of the wave? s / m 4 s 5 m 20 t d v = = =...
