Question

Based on the equation, determine what happens to the frequency if the period were to change from 0.2 seconds to 0.5 seconds. A) It would invert. B) It would decrease. C) It would increase. Eliminate D) It would not change.

Answer 1

Frequency can be defined as the number of times an event occurs within a unit time. In the context of waves for example, frequency refers to the number of waves that pass through a point in a certain amount of time.

Mathematically, the frequency (f) is related to the time period (T) as-

f = 1/T

SI Unit of frequency is Hertz (Hz)

In the given example:

When T = 0.2 s; f = 1/0.2 = 5 Hz

When T = 0.5 s; f = 1/0.5 = 2 Hz

As T increases, f decreases

Ans: B) It would decrease
