What is measured from one crest of a wave to the next consecutive crest?
AIts wavelength
BIts amplitude
CIts frequency
DIts intensity
Answer & Solution
Correct answer: A. Its wavelength
1. The manner in which solar energy travels is described as waves.
2. The wavelength is the distance between consecutive points of a wave.
3. A single wave is measured from two consecutive points, such as crest to crest or trough to trough.
4. Measuring the amount of energy of a wave is done by measuring this wavelength.
