Parts of a transverse wave include: Crest - the point on the wave
Trough - the point on the wave
Wavelength - the from one crest to the n3ext crest, or one trough to the next trough
Amplitude - the of the wave from the midpoint to the highest point (crest) or the lowest point (trough)

Parts of a transverse wave include:

Crest - the highest point on the wave

Trough - the lowest point on the wave

Wavelength - the distance from one crest to the next crest, or one trough to the next trough

Amplitude - the displacement of the wave from the midpoint to the highest point (crest) or the lowest point (trough)

Explanation:

Use the internet Brother

- measure reactants precisely. ( first choice)

- stir to the reaction take place. ( second choice)

- wait patiently until the reaction completes. ( fourth choice)

- make sure to recover as much copper as possible. ( last choice)

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
