Commom Properties of Light Flashcards
Distance between identical points on consecutive waves
Wavelength
Number of waves that pass a point per unit time
Frequency
wavelength×frequency
Speed
Distance between origin and crest (through)
Amplitude
When the direction of the vibration of the particles is perpendicular to the direction of the wave propagation
Transverse wave
When the direction of the vibration of the particles is parallel to the direction of the wave propagation
Longitudinal wave
What are the 4 Wave Properties of Light
Reflection
Refraction
Diffraction
Interference
When a wave strikes an object and bounces off
Reflection
The angle of incidence is equal to the angle of reflection.
Law of Reflection
A ray of light that is pointing towards and striking a surface
Incident ray
A ray of light that bounces back from surface of reflection
Reflected ray
Rough surface
Diffusse Reflection
Smooth surfaces
Specular Reflection
Is the transfer of energy carried by heat waves to the particles of matter
Absorption
Is the reflection of light particles
Scattering
Bending of waves passing from one medium to another
Refraction
Size Scale: Mountain and building
Radio waves
Uses: Oven cooking, radar, aircraft navigation, terrain mapping etc.
Microwaves
Uses: Heating and drying, night vision, cameras, satellites etc.
Infrared
What the typical eye and film can see, photography etc.
Visible light
Photochemical and photoelectric effects, hardening cast in medicine
Ultraviolet
Medical examination of bones, teeth, and vital organs
X-ray
Nuclear research, geophysics, mineral exploration
Gamma Ray
Atom
X-ray
Viruses
Ultraviolet
Bacteria
Visible light
Nuclei
Gamma ray
Nuclear transition
Gamma ray
Electron transitions or braking
X-ray
Electron transitions within an atom
Ultraviolet
Oscillation due to heat energy or electron transitions within an atom
Visible light
Oscillation of atoms or molecules due to the absorption of heat energy
Infrared
Atoms or molecules are oscillated within klystron and magnetron tubes
Microwaves
Sparks or alternating current cause a radio antenna to oscillate the atoms with it to the correct frequency
Radio waves
AM and FM radio, television, mobile phones, magnetic resonance, imaging etc.
