Light And Matter Flashcards
A ? Is a thing
Particle
The ?? Of each object determines the colors it absorbs or ?
Material properties. Reflects.
A wave is a ? Revealed thru its interactions with particles
Pattern
Wavelength is the ? From one peak to the next
Distance
Wavelength X frequency=
Speed
Light is an
Electromagnetic wave. They are traveling ( light waves)!on both electronic and magnetic fields
The strength of force that a particle would feel at any point of space
Field
Speed of light represented by letter
c
300,000 km/s
Speed of light
The ? The wavelength the lower the frequency
Longer
The shorter the wavelength the ? The frequency
Higher
Cycles per second are called
Hertz , Hz
Light comes in individual pieces called
Photons. They have properties of BOTH particles and waves
The ? The wavelength of a photon , the higher the energy of the photons.
Shorter
The ? , ?, and ? Are all related because light travels through space at same ?
Wavelength, frequency, and energy. Speed
Atoms are not Indivisible because
They can be broken down intoSMALLER parts
Freely moving particles constitute a
Gas
Some water vapor (gas) is always ?
Present in ice or water
Average kinetic energy of a substance can be measured by
Temperature
Charged atoms (electrons leave because of collisions) are called
ions. hot ionized gas isPLASMa. (4th phase of matter)
Only charged particles can interact with light . T Or F
True
Atoms contain energy in ? ways
- Mass
Kinetic. Moving
Electrical potential energy. The arrangement of electrons around nuclei
