1. What is Frequency?

Frequency is the number of occurrences of a repeating event per unit of time. In physics, it's most often measured in hertz (Hz), which equals one cycle per second.

2. How Does the Calculator Work?

The calculator uses the frequency formula:

Where:

• \( f \) — Frequency in hertz (Hz)
• \( T \) — Period in seconds (s)

Explanation: Frequency and period are inversely related. As the period increases, frequency decreases, and vice versa.

3. Importance of Frequency Calculation

Details: Frequency calculations are fundamental in physics, engineering, electronics, and many other fields. They're used in designing circuits, analyzing waves, and understanding oscillatory systems.

4. Using the Calculator

Tips: Enter the period in seconds. The value must be positive (T > 0). The calculator will compute the corresponding frequency in hertz.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between frequency and period?
A: Frequency measures how often something happens per second, while period measures the time between occurrences. They are inversely related.

Q2: What are common frequency units?
A: The SI unit is hertz (Hz). Other units include kilohertz (kHz), megahertz (MHz), and gigahertz (GHz).

Q3: Can frequency be calculated from wavelength?
A: Yes, if you know the wave speed (v): f = v/λ, where λ is wavelength.

Q4: What's the human hearing frequency range?
A: Typically 20 Hz to 20,000 Hz, though this varies by individual and decreases with age.

Q5: How is frequency used in radio?
A: Different radio stations broadcast at different frequencies, allowing receivers to tune to specific stations.
