Waves and Electromagnetic Spectrum (Rev1) Flashcards
Peak of crest
Top of wave
Trough
Bottom of wave
Amplitude
Distance between the line and peak
Wavelength
Distance between the peaks or troughs of 2 waves
Period (T)
The time taken in seconds for one complete wave to pass a point
Frequency (f)
The number of cycles per second. Measured in Hertz (Hz)
T=
F
F=
T
Wave equation
V = f x wavelength (h)
Longitudinal Waves
Oscillations are parallel to the direction in which the wave transfers (sound waves)
Transverse Waves
Oscillations are perpendicular to the direction in which the wave transfers energy
Electromagnetic Waves (speed)
Travel at speed of light v=3x10*8 m/s
Electromagnetic Waves (travel)
Can travel through a vacuum
Travel in straight lines
Electromagnetic Waves (types)
All transverse
Electromagnetic Waves (energy)
Electromagnetic waves with high frequency have high energy, while low frequency waves have low energy
