Science
produced after an optimal interaction of photons and electric field
Electromagnetic Waves
used to identify waves according to its frequency and wavelengths
EM Spectrum
smaller frequency than microwaves
Radio waves
frequency of radiowaves ranges from 30-300 MHz
Very High Frequency
frequency 300 MHz - 300 GHz‚ wavelength 1mm to 1m
Microwaves
uses of — were Remote sensing, RADAR, Bluetooth‚ Wi Fi‚ GPS
Microwaves
only type of EM waves that can be seen by naked eye
Visible light
it’s wavelength describes as tiny wavelengths
x-ray
allows to penetrate through matter because it carries small amount of energy
soft x-ray
the x-ray was called roentgenogram because of —
Wilhelm Conrad Roentgen
most of it came from the sun
Ultraviolet Radiation
its uses were blacklights‚ money security and medical equipment sterilization
UV waves
types of radiation that cannot penetrate the organism's cell
non-ionizing radiation
formed image behind the mirror‚ cannot projected on screen
virtual image
reversal image formed in plane mirrors
lateral inversion
composed mainly of iron nickel and alloy
outer core
dense thin layer
oceanic crust
boundary between the layers of the Earth
Seismic discontinuity
boundary between mantle and crust
Mohorovicic Discontinuity
molten rocks that has reached the Earth's surface
Lava
he proved the existence of energy beyond violet spectra of visible light
