5.4 Electromagnetic Waves

Made of vibrating electric and magnetic fields that can move at the speed of light. They do not need to travel through a medium.

• Tidal Wave

• Electromagnetic Waves

• Mechanical Wave

• Wavelength

light shines on metal and knocks some electrons off the metal

• Amplitude

• Frequency

• Photoelectric Effect

• Rarefactions

slits are left in horizontal or vertical directions to filter out some of the radiation

• frequency sunglasses

• amplitude sunglasses

• longitudinal sunglasses

• polarized sunglasses

the complete range of electromagnetic waves in order of increasing frequency

• electromagnetic spectrum

• amplitude spectrum

• polarized spectrum

• stream spectrum

longest wavelength and lowest frequency on the spectrum

• infrared rays

• radio waves

• visible light

• ultraviolet rays

One spot to the right of radio waves on the spectrum - shorter wavelengths and higher frequencies than radio waves

• microwaves

• ultraviolet rays

• visible light

• gamma rays

One spot to the right of microwaves on the spectrum - shorter wavelengths and higher frequencies than microwaves
