Question

multiple choice question
which defines wavelength?
the distance between equivalent points on a continuous wave
the number of waves that pass a point per second
the distance between the trough and the crest of a wave
the time it takes for a complete cycle of a wave to pass a given point

Explanation:

• Wavelength is defined as the distance between equivalent points (such as two consecutive crests or two consecutive troughs) on a continuous wave.
• The number of waves that pass a point per second is the frequency.
• The distance between the trough and the crest of a wave is related to the amplitude (half of this distance is the amplitude).
• The time it takes for a complete cycle of a wave to pass a given point is the period.

Answer:

the distance between equivalent points on a continuous wave
