Question 1

What are radio frequency bands?

Accepted Answer

VLF: 3-30 kHz, MF: 300 kHz-3 MHz, HF: 3-30 MHz, VHF: 30-300 MHz, UHF: 300 MHz-3 GHz.

Question 2

What frequencies do radio stations use?

Accepted Answer

AM: 530-1710 kHz, FM: 88-108 MHz. Higher FM frequencies give better audio quality.

Question 3

What's the relationship between frequency and wavelength?

Accepted Answer

They're inversely related: wavelength × frequency = wave speed. For sound in air: wavelength (m) ≈ 343 / frequency (Hz).

Question 4

Why use Hz vs RPM?

Accepted Answer

Hz (cycles per second) is universal for waves and oscillations. RPM (revolutions per minute) is more intuitive for rotating machinery and engines.
