100
This is the distance from crest to crest of a wave
What is wavelength?
100
This is the small part of the electromagnetic spectrum humans can see.
What is visible light?
100
When energized electrons fall back to lower energy levels, they release this.
What is light?
100
In Bohr’s model, electrons move between fixed ________ levels.
What are energy levels?
100
This equation relates speed of light, wavelength, and frequency.
This equation relates speed of light, wavelength, and frequency.
200
This is the number of wave cycles that pass a point each second.
What is frequency?
200
Red light has this kind of wavelength compared with blue light.
What is a longer wavelength?
200
A prism or diffraction grating separates light into this.
What is a spectrum?
200
This happens when an electron absorbs energy and moves to a higher energy level.
What is excitation?
200
This equation relates the energy of a photon to frequency.
What is E = hν?
300
These two properties are inversely related for light.
What are wavelength and frequency?
300
These three types of radiation are ionizing in large doses.
What are ultraviolet, X-rays, and gamma rays?
300
This is the pattern of specific lines produced by an element when its electrons emit light.
What is an atomic emission spectrum?
300
This model says electrons do not travel in exact paths but in probable regions.
What is the quantum mechanical model?
300
If wavelength increases, this happens to frequency.
What is frequency decreases?
400
This model explains many properties of light, including interference and refraction.
What is the wave model of light?
400
This type of radiation is used in microwave ovens and is strongly absorbed by water molecules.
What are microwaves?
400
No two elements have the same one of these, so scientists can identify elements with it.
What is an emission spectrum?
400
This term describes the region where an electron is most likely to be found.
What is the electron cloud?
400
Using c = λν, find the wavelength of light with frequency 5.09 × 10^14 Hz.
What is 5.89 × 10^-7 m?
500
In the equation c = λν, this symbol represents the speed of light.
What is c?
500
These are the shortest-wavelength, highest-energy waves on the electromagnetic spectrum.
What are gamma rays?
500
The wavelengths of spectral lines are those of an element
What is characteristic?
500
The wave model could not explain this effect, which helped support the particle model of light.
What is the photoelectric effect?
500
This constant, 6.626 × 10^-34 J·s, is used in photon energy calculations.
What is Planck’s constant?
