Flashcards do conjunto (12)
- 1Geocentric Modelthe belief that the Sun, Moon, planets and stars all orbited the Earth in perfect circles
- 2Heliocentric Modelstates that the Earth and planets all orbit the Sun at the centre of the Universe (replaced the Geocentric model)
- 3Galileo's observations of Jupitershowed not everything was in orbit around the Earth proving the Geocentric model wrong
- 4WavelengthThe distance from one peak to the next
- 5FrequencyHow many complete waves pass a point in a second (measured in Hz)
- 6AmplitudeThe height of the wave
- 7Speed (m/s)Frequency (hz) x Wavelength (m)
- 8Wave speed (m/s)Distance (m) / Time (s)
- 9Transverse WavesS-waves on strings and springs e.g. ripples on water. Includes all EM waves and Light
- 10Longitudinal WavesP-waves including sound and ultrasound e.g. a slinky spring
- 11Angle of reflection (r) =Angle of incidence (I)
- 12EM WavesTravel slower in a denser medium
