Ans- longitudinal waves

2.Which type of wave carries the most energy?
Ans- high frequency, short wavelength

3.What change takes place in a wave when the frequency of the wave increases?
Ans- A greater number of wavelengths pass a point per given second

4.In which type of wave do the particles in a medium move perpindicular to the direction that the wave moves?
Ans- transverse waves
