Electromagnetic Spectrum Flashcards
What was the major problem of Rutherford’s model?
Negatively charged electrons outside the nucleus are attracted to positively charged nucleus
Niels Bohr started working with what?
Hydrogen
What occurred when Bohr passed an electric current through a vacuum tube containing hydrogen?
a characteristic pink glow
When emiited light is passed through a prism…
it is separated into 4 specific colors
Electromagnetic Radiation:
form of energy that exhibits wavelike behavior as it travels through space
All forms of electromagnetic radiation form:
Electromagnetic Spectrum
Maxwell demonstrated that:
electric/magnetic fields travel though space as waves moving at speed of light
Light:
electromagnetic radiation made of electric/ magnetic fields
Electromagnetic Spectrum:
arrangement of all electromagnetic waves by decreasing wavelength (increasing frequency)
Increasing frequency=
=decreasing wavelength
=high energy
decreasing frequency=
=increasing wavelength
=low energy
ROYGBIV
red, orange, yellow, green, blue, indigo, violet
Wavelength:
measure crest to crest or trough to trough
symbol: upside-down y
frequency:
of waves that pass a given point in a specific time (1 sec)
Symbol: (v)
What is frequency measured in?
cycle/s or Hertz (Hz)
s-1 or (1/s)
