Characteristics of Waves

Below figure shows that the shape of a part of a long string in which transverse waves are produced. Which pair of particles are in phase?

In a longitudinal wave there is a state of decided maximum compression at a point. The frequency of wave is 50 Hz. After what time will the same point be in the state of maximum rarefaction?

What type of waves do you expect in vacuum

The waves are

The wavelength of ultrasonics in air is of the order of
