Open Question: 9th grade wave speed science problems?
Please explain all work! Thank you!
A 4.Z Hz periodic wave has a wavelength of 2.2 meters. What is the speed of the wave? What is the period of the wave?
A 440-Hz note is generated by a hammer hitting a string on a piano. If the length of the string is 0.77 meters in length, what is the speed of sound in the room? How quickly does the string vibrate?
