Three traveling sinusoidal waves are on identical strings, with the same tension. The mathematical forms of the waves are y1(x,t) = ymsin(3x - 6t) , y2(x,t) = ymsin(4x - 8t) , and y3(x,t) = ymsin(6x - 12t) , where x is in meters and t is in seconds. Match each mathematical form to the appropriate graph below.
Experimental Studies
Research methodologies that involve the manipulation of variables to observe the effect on another variable, typically within a controlled environment.
Causality
The relationship between cause and effect where one event (the cause) leads to the outcome (the effect), fundamental to scientific and philosophical inquiry.
Longitudinal Research
A research design that involves repeated observations of the same variables, such as people or situations, over a period of time, ranging from several years to decades.
Observing
The act of carefully watching someone or something, often to gain information.
