Interpretation: The difference between the frequency and the speed of a wave is to be explained.
Concept Introduction:The frequency of a wave is the number of waves in unit time while the speed of a wave is the distance covered by a wave in unit time.

Answer to Problem 4RQ
Wave frequency is a fundamental characteristic of a wave but wave speed is not a fundamental characteristic and depends upon the point of consideration. The unit of wave frequency is s-1 while the wave speed unit is ms-1.
Explanation of Solution
The difference between the wave frequency occurs due to the different points of observation. In wave speed, the distance travelled by a point of the wave is calculated while in wave frequency, the number of waves passing through a particular point are observed.
