Module 2.1 Lesson 1: The Electromagnetic Spectrum Flashcards
A disturbance that travels through a medium from one location to another location, transferring energy.
Wave
Waves that have both electric and magnetic component and can travel through matter or a vacuum.
Electromagnetic Spectrum
Energy transmitted as electromagnetic waves.
Radiation
Highest point of a wave.
Crest
Lowest point of a wave.
Trough
Height of a wave.
Amplitude
Length of a wave from crest to crest.
Wavelength
Number of crests that pass a given point within a second.
Frequency
Amount of time it takes for one wavelength to pass a point.
Period
A German theoretical Physicist
Max Planck
Smallest unit of any substance
Molecule
When energy transfers, it moves in set amounts called?
Quanta
It was devised in 1900.
Planck’s Constant
Arrangement of electromagnetic waves based on their wavelengths.
Electromagnetic Spectrum
The vibration of particles in the medium is parallel to the direction of propagation of the wave.
Longitudinal waves
