Electromagnetic Waves and Spectrum Quiz

Study Notes

Electromagnetic Waves

James Maxwell's theory predicted the existence of electromagnetic waves.
Heinrich Hertz confirmed the existence of EM waves in 1887.
EM waves are transverse waves, meaning the electric and magnetic fields oscillate perpendicular to the direction of wave propagation.
All EM waves travel at the speed of light in a vacuum, which is approximately $3 \times 10^{8}$ m/s.
The electromagnetic spectrum is a classification of EM waves based on their frequency and wavelength.

The Electromagnetic Spectrum

The electromagnetic spectrum ranges from gamma rays with the highest energy to radio waves with the lowest energy.
The spectrum contains: gamma rays, X-rays, ultraviolet rays, visible light, infrared rays, radar, FM, TV, shortwaves, and AM waves.
Visible light occupies a relatively small portion of the electromagnetic spectrum and is represented by a rainbow of colors.

Radio Frequency Identification (RFID)

RFID uses radio waves to tag and identify objects, especially vehicles.
RFID systems are prevalent in Electronic Toll Collection (ETC) for fast and efficient payments.

Wi-Fi

Wi-Fi uses radio waves for wireless connectivity in local networks and internet access.

Importance of Electromagnetic Waves

Electromagnetic waves are crucial for technological advancements in communication, transportation, medicine, space exploration, and various industries.
