1. What is Frequency and Wavelength?

Frequency (f) is the number of wave cycles per second, measured in Hertz (Hz). Wavelength (λ) is the distance between consecutive wave peaks, measured in meters (m). They are inversely related through the wave speed (V).

2. How Does the Calculator Work?

The calculator uses these fundamental equations:

Where:

• \( f \) — Frequency in Hertz (Hz)
• \( \lambda \) — Wavelength in meters (m)
• \( V \) — Wave speed in meters per second (m/s)

Explanation: The calculator requires you to input the wave speed and either frequency or wavelength to calculate the missing value.

3. Importance of Frequency and Wavelength

Details: Understanding the relationship between frequency and wavelength is crucial in physics, engineering, telecommunications, and many other fields where wave phenomena are important.

4. Using the Calculator

Tips: Enter the wave speed (V) in m/s and either frequency or wavelength. The calculator will compute the missing value. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of sound in air?
A: Approximately 343 m/s at 20°C (68°F), but varies with temperature and medium.

Q2: What is the speed of light?
A: Approximately 299,792,458 m/s in a vacuum.

Q3: How are frequency and wavelength related?
A: They are inversely proportional when wave speed is constant - higher frequency means shorter wavelength and vice versa.

Q4: What are typical frequency ranges?
A: Audible sound: 20Hz-20kHz, Radio waves: 3kHz-300GHz, Visible light: 430-750THz.

Q5: Why does wavelength matter?
A: Wavelength determines how waves interact with objects and is crucial for antenna design, diffraction effects, and more.
