AM vs FM Radio Waves & Frequencies

Electromagnetic Waves Overview

• AM (amplitude modulation) and FM (frequency modulation) radio waves are transverse waves.
• They consist of electric and magnetic disturbances, classified as electromagnetic radiation.
• Travel speed: $3.00 \times 10^8 \text{ m/s}$.

Frequency Ranges

AM Radio

• Kilohertz ($10^3 \text{ Hz}$) range.
• Frequency range: $545 \text{ kHz}$ to $1605 \text{ kHz}$.
• Example: $990 \text{ kHz}$.

FM Radio

• Megahertz ($10^6 \text{ Hz}$) range.
• Frequency range: $88 \text{ MHz}$ to $108 \text{ MHz}$.
• Example: $98.3 \text{ MHz}$.

Television Channels

• Channels 2-6: Utilizes frequencies between $54 \text{ MHz}$ and $88 \text{ MHz}$.
• Channels 7-13: Utilizes frequencies between $174 \text{ MHz}$ and $216 \text{ MHz}$.
