36. Indicate "T" for transverse wave, "L" for longitudinal wave, and "E" for electromagnetic wave Energy causes a medium to vibrate back and forth parallel to the forward direction the energy moves Sound is an example This wave does not require any medium to travel which allows it to travel in outer space People doing \"the wave" in a stadium act like a medium with this wave moving through. Water waves are an example Energy causes a medium to vibrate up and down in place as the energy moves forward through it. Compressional Wave is another name for this type of wave. 37. What is the velocity of a wave with 35 oscillations, each with a span of 4.5 m, ocecurring in 22 seconds? 38. A tuning fork is used to produce a sound at 883 Hz. The wave travels at 343 m/s. What is the wavelength of this sound? 39. Answer the following questions using this diagram: i. Which has the largest frequency? ii. Did this wave have a larger or smaller wavelength? iii. How many wavelengths are shown with: Y7 W? X? iv. What two waves that have the same amplitude? & v. Which wave has the smallest frequency? vi. What is the wavelength of \"X? What is the wavelength of \"Y 7 40. Friends honk their car horn the entire time they pass my home. As the car gets farther away, the sound becomes (higher or lower ) in pitch and the frequency gets (bigger or smaller). This change in sound is a result of W X @)
