(la) What is the wavelength of a 1.02 MHz ultrasound wave travelling through aluminum? (the speed of sound in aluminum is 6420 m/s) Submit Answer Tries 0/10 (1b) What frequency of electromagnetic wave in vacuum would have the same wavelength as the ultrasound wave above? Submit Answer Tries 0/10 (2) A car driving along a highway at speed of 23.4 m/s strays onto the shoulder. Evenly spaced parallel grooves called rumble strips are carved into the pavement of the shoulder. Rolling over the rumble strips causes the cars wheels to oscillate up and down at a frequency of 68.0 Hz. How far apart are the centers of adjacent rumble-strip grooves?
