Period and frequency have a special relationship called?

• A. Inverse
• B. Direct Proportion
• C. Reciprocal
• D. Linear Relationship

Answer: (C)

The main idea is that period and frequency are reciprocals of each other. The period is the time for one complete cycle, while frequency counts how many cycles happen per unit time. They are connected by f = 1/T, so their product is always 1. That means if the period doubles, the frequency halves, and vice versa (for example, T = 2 s gives f = 0.5 Hz; T = 4 s gives f = 0.25 Hz). This is not a direct or linear relationship where both grow together; instead, one increases as the other decreases in a reciprocal way. While you might hear “inverse,” the precise description here is reciprocal, since the two values multiply to a constant of 1.
