Kilohertz (Thousand Hertz)

Introduction : Equal to 1,000 hertz, kilohertz is commonly used for audio frequencies, radio signals, and electronic oscillations. It bridges everyday frequencies between sound and radio waves.

History & Origin : Became standardized with metric prefixes in the 20th century. Early radio engineers adopted kHz for AM radio bands (535–1605 kHz) and audio equipment specifications.

Current Use : Key for AM radio broadcasting, ultrasound imaging (2–18 kHz), and analog signal processing. Used in musical instrument tuners and vintage computer clock speeds.

Megahertz (Million Hertz)

Introduction : The megahertz measures millions of cycles per second, crucial for FM radio, early computers, and wireless communications. It represents mid-range electromagnetic frequencies.

History & Origin : Gained prominence with FM radio (88–108 MHz) in the 1930s and early microprocessors (1–10 MHz in the 1970s). Became a household term with personal computer clock speeds.

Current Use : Dominates FM radio, TV signals, and short-range wireless (Wi-Fi 2.4 GHz). Used in older CPU speeds (e.g., 4.77 MHz in IBM PC) and medical diathermy devices.
