1. What is the Wavelength Formula?

The wavelength formula calculates the wavelength of electromagnetic radiation from its frequency using the relationship between the speed of light, frequency, and wavelength.

2. How Does the Calculator Work?

The calculator uses the wavelength formula:

Where:

• \( \lambda \) — Wavelength (meters)
• \( c \) — Speed of light (3 × 10⁸ m/s)
• \( f \) — Frequency (Hz)

Explanation: The formula shows the inverse relationship between frequency and wavelength - as frequency increases, wavelength decreases, and vice versa.

3. Importance of Wavelength Calculation

Details: Calculating wavelength is essential in various fields including telecommunications, optics, astronomy, and quantum physics. It helps determine the properties of electromagnetic waves and their interactions with matter.

4. Using the Calculator

Tips: Enter the frequency in Hertz (Hz). The value must be greater than 0. The calculator will compute the corresponding wavelength in meters.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light constant?
A: The speed of light in vacuum is approximately 3 × 10⁸ meters per second (299,792,458 m/s exactly).

Q2: How does wavelength relate to energy?
A: For photons, energy is inversely proportional to wavelength (E = hc/λ), where h is Planck's constant.

Q3: What are typical wavelength ranges?
A: Radio waves have wavelengths from meters to kilometers, visible light from 380-750 nm, and gamma rays have wavelengths smaller than atoms.

Q4: Can this formula be used for all electromagnetic waves?
A: Yes, this formula applies to all electromagnetic radiation in vacuum. In other media, the speed of light changes, affecting wavelength.

Q5: How is frequency measured?
A: Frequency is typically measured in Hertz (Hz), which represents cycles per second. Radio frequencies are often in kHz, MHz, or GHz.
