📊 Frequency Calculator

Convert between frequency and period, calculate wavelength, RC time constant, and 555 timer frequency.

📊 Frequency • Period Converter

Frequency

Period (T = 1/f)

📊 Wavelength Calculator

Frequency

Medium

Wavelength (? = v/f)

📊 RC Time Constant (t = RC)

Resistance (R)

Capacitance (C)

Key Formulas

Period: T = 1/f (seconds)
Wavelength: • = v/f (v = speed of light = 3₹108 m/s in free space)
RC Time Constant: t = R • C (capacitor charges to 63.±2% in one t)
Cutoff frequency of RC filter: fc = 1/(2p�R°C)
