1. What is the MHz to nm Conversion?

The MHz to nm conversion calculates the wavelength of electromagnetic radiation from its frequency. This is particularly useful in fields like optics, radio astronomy, and telecommunications.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \lambda \) — Wavelength in nanometers (nm)
• \( f \) — Frequency in megahertz (MHz)
• \( 3 \times 10^{11} \) — Conversion factor (speed of light in nm/s divided by 1,000,000 for MHz)

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

3. Importance of Wavelength Calculation

Details: Knowing the wavelength is essential for designing optical systems, understanding wave propagation characteristics, and analyzing spectral data.

4. Using the Calculator

Tips: Enter frequency in MHz (must be a positive number). The calculator will compute the corresponding wavelength in nanometers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3e11?
A: It comes from the speed of light (3e8 m/s) converted to nm/s (3e17) and divided by 1e6 to account for MHz.

Q2: Can this be used for all electromagnetic waves?
A: Yes, this formula applies to all EM radiation, from radio waves to gamma rays.

Q3: What's the range of validity for this formula?
A: It works for any positive frequency, though practical applications typically range from radio to visible light frequencies.

Q4: How accurate is this calculation?
A: It's mathematically exact, assuming the speed of light in vacuum. For other media, the speed would need adjustment.

Q5: What if I need to convert from nm to MHz?
A: Simply rearrange the formula: \( f (MHz) = \frac{3 \times 10^{11}}{\lambda (nm)} \)
