question: If there are less crests coming through, there will be _____ wave frequency.
choices.text: more less
choices.label: A B
para: Wave frequency can be measured by counting the number of crests or compressions that pass the point in 1 second or other time period. The higher the number is, the greater is the frequency of the wave.
