Which of the following statements is correct?

If the constituents of the medium oscillate perpendicular to the direction of wave propagation, we call the wave a longitudinal wave.
If the constituents of the medium oscillate along the direction of wave propagation, we call the wave a transverse wave.
Frequency of a wave is the number of oscillations of each constituent particle in the vibrating medium per minute.
The minimum distance between two points in a wave having the same phase at a particular instant of time is called the wave length.

Solution:

The wavelength of a wave is the minimum distance between two points having the same phase. It is denoted by

λ

and measured in meters.
