Semester Final Flashcards
a disturbance that transfers energy from one place to another without requiring matter to move the entire distance.
Wave
a substance through which a wave moves
Medium
a wave such as a sound or seismic wave that transfers kinetic energy through matter
Mechanical Wave
A wave which the disturbance move at a right angles to the direction of the wave.
Transverse Wave
a wave in which the disturbance moves in the same direction as the wave.
Longitudinal Wave
the highest point in a wave
Crest
the lowest point in a wave
Trough
the distance from one wave crest to the next wave crest
Wave length
the number of waves that pass a fixed point in a given period of time
Frequency
the range of all electromagnetic frequencies
Electromagnetic Spectrum
the passage of waves through a medium
Transmission
the disappearance of wave into a medium. The energy transferred by a wave is converted into another form of energy.
Absorption
the act of noting and recording an event, characteristic, or anything detected.
Observation
the process of collecting evidence
Investigation
a tentative explanation for an observation or phenomenon, an if then statement
Hypothesis
the end of a scientific investigation, how it turns out
Conclusion
a test, trial, or tentative procedure, an act or operation for the purpose of discovering something unknown
Experiment
what youβre are trying to solve in a scientific investigation
Problem
the answer to a scientific problem or investigation
Solution
anything that was alive or was once alive
Biotic factors
Nonliving parts of an ecosystem
Abiotic factors
any living organism that is so similar that it can breed and produce offspring that can produce offspring.
Species
the number of a particular species living in a particular area.
Population
