A slowly moving engine bumps into a string of coupled railroad cars standing on a siding. A wave pulse is transmitted down the string of cars as each one bumps into the next one. What type of wave is this? Multiple Choice a mix of transverse anditudinal

At sporting events the crowd sometimes generates a "wave" that propagates around the stadium. What type of wave is this?

If you increase the speed of a wave on a Slinky by increasing the tension, but keep the same frequency of back-and-forth motion, how does the wavelength change? Multiple Choice
