it is a research design where all data is collected from samples (of people, documents, etc.) at least two times .
Longitudinal research approach.
A longitudinal survey is a research method that involves collecting data from the same group of participants over an extended period. This allows researchers to track changes and trends within the group over time. Longitudinal surveys are often used to study development, behavior, or other changes that occur over the course of a lifetime.
CLASSIFICATION OF WAVESWaves may be classified in two:According to nature:1. Electromagnetic Wave2. Mechanical WaveAccording to direction of the propagation1. Transverse Wave2. Longitudinal Wave
The most commonly used research design is the experimental design, where researchers manipulate one or more variables to observe their effect on an outcome. This design allows for causal relationships to be established between variables.
Kingsley Davis's definition of sociology as the "study of social interactions and institutions" was formulated in the mid-20th century. There is no specific year noted for this definition, as it was a foundational concept in sociology that influenced the discipline's development over time.
A sound wave's structure, by definition, is a longitudinal one. More specifically, it is "a longitudinal wave in an elastic medium."
longitudinal design
longitudinal axis: An axis along the lengthwise direction of the figure or body, usually passing through its center of gravity.
The definition for the word longitudinal is "running lengthwise rather than across."

It is not so much longitudinal vs. transverse - it is the type of wave. Mechanical waves, by definition, travel through matter. That includes sound waves. Mechanical waves, however, can be both longitudinal and transverse - and both require a medium.

A longitudinal wave is a type of wave in which the vibrations occur in the same direction as the wave's propagation. This means that the particles of the medium move parallel to the direction of energy transfer. Examples of longitudinal waves include sound waves and seismic waves.
