Conversion Tips
1 Hz = 1 cycle per second
1 Hz = 60 rpm (revolutions per minute)
Higher frequency = shorter period
Angular frequency in rad/s = 2π × frequency in Hz
Understanding Frequency and Its Units
What is Frequency?
Frequency describes how often a periodic event occurs in a given time interval. It measures the number of cycles, oscillations, or repetitions per unit time. Higher frequency means more cycles occur in the same time period.
Types of Frequency
- •Linear Frequency (f): Cycles per second, measured in Hertz
- •Angular Frequency (ω): Radians per second, used in rotational motion
- •Rotational Frequency: Revolutions per minute (rpm), common in mechanical systems
Unit Relationships
1 Hz =
• 60 rpm (revolutions per minute)
• 2π rad/s (radians per second)
• 360 deg/s (degrees per second)
• 1 cycle/second
Common Applications
- •Electronics: AC power (50/60 Hz), radio waves
- •Mechanics: Engine RPM, vibration analysis
- •Optics: Light frequency determines color
- •Medicine: Heart rate, brain waves
Frequency Spectrum Examples
Audio Range
Human hearing: 20 Hz - 20 kHz. Musical notes, speech, and audio equipment operate in this frequency range.
Radio Waves
AM radio (530-1700 kHz), FM radio (88-108 MHz), WiFi (2.4/5 GHz), and cellular frequencies.
Visible Light
400-700 THz range. Red light (~430 THz) to violet light (~750 THz). Frequency determines color perception.
X-rays & Gamma
Medical X-rays (30 PHz - 30 EHz) and gamma rays (>30 EHz) used in medical imaging and cancer treatment.
