It is true that in the science laboratory setting, scientists often struggle to achieve valid results. A possible solution for this dilemma is to repeat the procedure for several trials.

Explanation:

When we do experiments it's a good idea to do repetitious trials, that is, do the same test lots of times. When we do several trials of the same experiment, we can make sure that our results are compatible and not altered by accidental events. Various trials can be done at one time so that a scientist can get a valid result of their observations.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
