Frequency Calculator
Convert between frequency and wavelength using the speed of light
How to use this calculator:
📡 Radio Waves
Use case: Calculate frequency from wavelength for radio communications.
Example: λ=1m → f=299,792,458 Hz
💡 Light Calculations
Use case: Work with electromagnetic spectrum and light properties.
Example: f=5×10¹⁴ Hz → λ=600nm (orange light)
Frequency ↔ Wavelength Converter
Enter either wavelength or frequency for real-time conversion
Formulas:
f = c / λ (Frequency from wavelength)
λ = c / f (Wavelength from frequency)
where c = 299,792,458 m/s (speed of light)
Examples: 1 (radio), 0.0005 (visible light), 1e-9 (X-ray)
Examples: 100000000 (FM radio), 5e14 (visible light)
Common Examples:
FM Radio (100 MHz):
Frequency: 100,000,000 Hz → Wavelength: 2.998 m
Visible Light (Red):
Wavelength: 7×10⁻⁷ m (700 nm) → Frequency: 4.28×10¹⁴ Hz
Microwave (2.45 GHz):
Frequency: 2,450,000,000 Hz → Wavelength: 0.122 m (12.2 cm)
Use Cases:
Radio Communications: Calculate antenna lengths and frequency allocations
Spectroscopy: Convert between wavelength and frequency for light analysis
Telecommunications: Design wireless systems and understand signal propagation
