The frequency of a wave increases. If the speed of the wave remains constant, what happens to the distance between successive crests? a. The distance between successive crests remains constant. b. The distance between successive crests increases. c. The distance between successive crests decreases.

Period: The time it takes to make a complete wave or vibration is measured in seconds (s) and is represented by an uppercase T. It is also the time it takes for a particle to perform a complete oscillation.

Frequency: It is the number of cycles produced per second. The frequency is indicated by the lowercase letter f. It is measured in cycles / second or Hertz (Hz). It coincides with the number of oscillations per second that a point makes when it is reached by the waves and shares an inverse relationship with the period (T).

The only way to increase the frequency of a wave at constant speed is to generate an increase in its period.

This means decreasing the distance between successive waves.
