Electromagnetic Spectrum Flashcards
(8 cards)
What is a medium
A medium is any physical substance in which energy can be transferred through
Electromagnetic wave
A wave that has both electric and magnetic parts
Electromagnetic spectrum
A range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies
What is the order of the electromagnetic spectrum
Radio waves, microwave, infrared, visible, ultraviolet, x-ray, gamma.
From radio waves having the longest radio waves have the least amount of energy and lowest frequencies and gamma rays having the most energy because of how short their wavelengths are.
Visible light
The visible region of the electromagnetic spectrum. The range of wavelengths that trigger brightness and colour perception in humans.
Visible light spectrum sequence
Red, orange, yellow, green, blue, indigo, and violet
From red being the least energetic and is slowed the least when white light passes through a prism and violet light being the most energetic and is slowed the most when white light passes through a prism.
When light hits and object it can either be…
Reflected
Absorbed
Transmuted
These colours determine what colours we see
Incident light
A ray of light that hits a surface
