Wavelength
This is the term for the distance between two consecutive crests of a wave.
What is wavelength?
Frequency is measured in this unit, equal to cycles per second.
What are hertz (Hz)?
When an electron drops from a higher energy level to a lower one, it emits this.
What is a photon of light?
The part of the EM spectrum humans can see.
What is visible light?
The region of space where an electron is likely to be found
What is an orbital?
As wavelength decreases, this property of a wave increases.
What is frequency?
This equation shows the inverse relationship between frequency and wavelength.
What is c=λν?
In absorption, energy is required for an electron to make this type of transition.
What is a jump to a higher energy level?
This type of EM wave has the shortest wavelength and the highest energy.
What are gamma rays?
This principle states that you cannot know both the exact position and momentum of an electron at the same time.
What is the Heisenberg Uncertainty Principle?
Red light has a longer wavelength than this color at the opposite end of the visible spectrum.
What is violet?
High-frequency waves carry this type of energy compared to low-frequency waves.
What is more energy?
Bohr’s model successfully explained the emission spectrum of this element.
What is hydrogen?
These waves, longer than infrared, are commonly used for cooking and radar.
What are microwaves?
Quantum theory states that electrons occupy allowed energy states and behave as both particles and waves. Name the dual concept describing this behavior
What is wave-particle duality?
Among microwaves, X-rays, and visible light, this type has the longest wavelength.
What are microwaves?
Among radio waves, ultraviolet light, and infrared, this one has the highest frequency.
What is ultraviolet?
What is required for an electron to move from an excited state to the ground state?
absorption of energy
What color light has a wavelength of 677 nm?
Red
Schrödinger’s wave equation treats electrons as these rather than particles in fixed orbits.
What are particles traveling through space as waves?
A wave travels at the speed of light (3.00 × 10⁸ m/s) and has a frequency of 5.00 × 10¹⁴ Hz. Calculate its wavelength
What is λ=3.00×108/5.00×1014 = 6.0×10−7 m
Calculate the frequency of light with a wavelength of 3.20 × 10⁻⁷ m.
What is ν=3.00×108/3.20×10−7=9.38×1014 Hz
Which has the longest wavelength infrared or UV light?
Infrared
Calculate the energy of a photon with frequency 6.50 × 10¹⁴ Hz.
What is E=4.31×10−19 J
What was the problem with Bohr's model of the atom?
What is It did not apply to elements with more than one electron?
