Light And Quantum Theory Flashcards
(26 cards)
Has a high frequency and a low wavelength
Blue light
The distance between identical points on successive waves
Wavelength
The emission and transmission of energy in he form of electromagnetic waves
Electromagnetic radiation
Related to the amount of energy the wave has
Amplitude
Elements absorb the same specific frequencies of light that they emit
Absorption spectrum
A continuous range of wavelengths
White light
What is wavelength measured in?
Nanometers
How can you identify elements
Atomic emission spectrum because it is unique for each element
In a vacuum what is electromagnetic waves frequency?
3 x 10^8
What is planck’s constant
6.626 x 10^-34
What is he formula for the speed of a wave
Speed=wavelength x frequency
Half the vertical distance from crest to trough
Amplitude
Who concluded that light has particle like behavior
Max Planck
Formula for the energy of a Quanta
Energy of a quanta= planck’s constant x frequency
Each portion has a unique frequency and wavelength
White light
The number of waves that pass through a particular point in 1 sec
Frequency
Some metal emit electrons when light of a specific or higher frequency shines on it
Photoelectric effect
Set of frequencies of electromagnetic waves emitted by atoms of an element
Atomic emission spectrum
Matter can gain or lose energy in small specific amount called what?
Quanta
A particle with no mass that carries a quantum of energy
Photon
Reflection and refraction
Wave behavior
Has a low frequency and a high wavelength
Red light
The minimum amount of energy that can be lost or gained by an atom
Quantum
Atomic emission spectrum
Photoelectric effect
Particle behavior
