1. What is GHz to nm Conversion?

The GHz to nm conversion calculates the wavelength of electromagnetic radiation from its frequency. This is particularly useful in fields like optics, telecommunications, and spectroscopy where both frequency and wavelength measurements are important.

2. How Does the Calculator Work?

The calculator uses the wavelength conversion formula:

Where:

• \( \lambda \) — Wavelength in nanometers (nm)
• \( f \) — Frequency in gigahertz (GHz)
• \( 3 \times 10^{17} \) — Conversion factor combining speed of light and unit conversions

Explanation: The equation converts frequency to wavelength using the fundamental relationship between these two properties of electromagnetic waves.

3. Importance of Wavelength Calculation

Details: Knowing both frequency and wavelength is essential for designing optical systems, analyzing spectral data, and working with electromagnetic radiation across different parts of the spectrum.

4. Using the Calculator

Tips: Enter frequency in GHz (must be positive value). The calculator will output the corresponding wavelength in nanometers.

5. Frequently Asked Questions (FAQ)

Q1: Why is 3×10¹⁷ used in the formula?
A: This combines the speed of light (3×10⁸ m/s) with unit conversions from meters to nanometers and from Hz to GHz.

Q2: What's the relationship between frequency and wavelength?
A: They are inversely proportional - higher frequency means shorter wavelength and vice versa.

Q3: Can this be used for all electromagnetic waves?
A: Yes, the relationship applies to all EM radiation, from radio waves to gamma rays.

Q4: What are typical GHz values for visible light?
A: Visible light ranges from about 400-800 THz (400,000-800,000 GHz), corresponding to 750-375 nm wavelengths.

Q5: How precise is this calculation?
A: It's mathematically exact, though real-world applications may require accounting for the medium's refractive index.
