To learn more about these waves, review the lesson Longitudinal Wave Lesson for Kids. This covers the following topics: What longitudinal waves are Where these waves get their energy Examples of longitudinal waves What transverse waves are and how they differ from longitudinal waves ...
Longitudinal waves are the mechanical waves in which the vibration of the particles takes place in the same direction as that of the wave. Sound waves, seismic waves are the examples of longitudinal waves.
Furthermore, the within-person and between-person correlations of grades and emotions derived from the RI-CLPM were equivalent to the between-person correlations for the single waves reported by Pekrun et al. (2017). However, the RI-CLPM between-person correlations were stronger than the ...
The average time-lag between adjacent waves was one year (M = 11.98 months; SD = 7.81 months), and it ranged from 1.38 to 36 months. All studies considered only one dimension of prejudice (mainly cognitive prejudice, followed by affective prejudice), with only Binder et al. (2009) ...
Importantly, “organised activities,” which indicates adult structure, was only simultaneously coded for 0.7%–1.1% and 0.57%–1.52% across waves of the mean time children were engaged in quiet and active play, respectively. These low percentages provide good evidence of construct validity for the...
Table A1, Table A2, Table A3 and Table A4 provide details of the variables selected from the different waves of the IYDS and YPOF studies to be combined into the current analysis. Below is a summary of measures and an example question for each construct. 2.3.1. Demographics Demographic ...
