1. What is the Frequency Formula?

The frequency formula calculates the number of occurrences of a repeating event per unit time. It is the reciprocal of the period (the time for one complete cycle).

2. How Does the Calculator Work?

The calculator uses the frequency formula:

Where:

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

Explanation: The formula shows that frequency is inversely proportional to the period. As period increases, frequency decreases and vice versa.

3. Importance of Frequency Calculation

Details: Frequency calculation is fundamental in physics and engineering, particularly in wave mechanics, electronics, and signal processing.

4. Using the Calculator

Tips: Enter the period in seconds (must be greater than 0). The calculator will compute the frequency in Hertz (Hz).

5. Frequently Asked Questions (FAQ)

Q1: What are common units for frequency?
A: The SI unit is Hertz (Hz), which equals cycles per second. Other units include kHz, MHz, GHz.

Q2: How does frequency relate to wavelength?
A: For waves, frequency and wavelength are inversely related through the wave speed: \( v = f \times \lambda \).

Q3: What is the human hearing frequency range?
A: Typically 20 Hz to 20,000 Hz (20 kHz), though this decreases with age.

Q4: What's the difference between angular frequency and frequency?
A: Angular frequency (ω) is measured in radians per second and equals \( 2\pi f \).

Q5: How is frequency measured in practice?
A: Using frequency counters, oscilloscopes, or spectrum analyzers for electronic signals.
