Electromagnetic Waves Flashcards
acts like a magnet
solenoid
created around a wire that conducts electric current
magnetic field
regions through which the push or pull of charged particles and magnets is exerted
electromagnetic wave
charged particles that can produce magnetic and electric fields
electrons
An electromagnetic wave is considered as what wave
transverse waves
both electric and magnetic fields oscillate ___________ to each other
perpendicular
electromagnetic wave travels at __________________
3x10^8 m/s
denoted ___, speed of light
c
speed of electromagnetic wave __ speed of light
=
Relationship between wavelength and frequency
inversely proportional
developed scientific theory
james clerk maxwell
-proved the existence of radiowaves
-german physicist
Heinrich hertz
discovered electromagnetic induction
Michael Faraday
discovered that a wire carrying electric current can attract or repel another wirer
Andre-marie Amphere
water, earthquake, sound waves are
mechanical waves
Can light be a mechanical wave?
Yes, but it does not require a medium to propagate
maximum field strength of the electric and magnetic field
Amplitude
waves per second a wavelength produce
frequency
measures the length of an individual wave in meters
wavelength
longest wavelength
lowest frequency, lowest amount of energy
shortest wavelength
highest frequency, highest amount of energy
bundles of wave energy
photons
electromagnetic waves are often arranged in order of wavelength and frequency aka
electromagnetic spectrum
ionizing radiation
ultraviolet
x-rays
gamma rays
non- ionizing radiation
radio wave
microwave
infrared radiation
visible light
