200
An electron in its normal orbit is said to be at this.
What is "ground state"?
300
The order of VISIBLE light from longest wavelength to shortest.
What is, red, orange, yellow, green, blue, indigo, violet?
300
The symbol for wavelength, and what it is called.

300
The unit for energy
What is, joules (J)?
300
When excited light from an element is passed through a prism, it produces a unique...
What is, line emission spectrum?
400
The form of light in this list that has the shortest wavelength:
x-ray, radio waves, infrared
What is, x-ray?
400
What is always the value for c?
3.00x108 m/s
400
Light that has higher frequency than blue light but less than ultraviolet.
What is, violet (or purple)?
400
The energy equation, rearranged to solve for frequency.
What is ...
E/h
400
Light can only be emitted by an electron when this occurs.
When the electron falls from excited to ground state.
500
The order of light forms on the electromagnetic spectrum, from HIGHEST energy to LOWEST energy.
What is--gamma, x rays, ultraviolet, visible light, infrared, microwaves, and radio waves?
500
The equation used to show the relationship between wavelength and frequency.
What is...?
500
The 3 forms of light that have shorter wavelengths than visible light.
What are, ultraviolet, x-ray, and gamma?
500
Light with a frequency of 4.35 x 1014 Hz carries energy. This is the calculation you would do to find that energy.
E = (6.626 x 10-34 Js) (4.35 x 1014 1/s)
500
The more energy levels an electron jumped when absorbing light, the ___________ the frequency will be of the emitted light released from the falling electron.
What is "higher"?
600
The form of light we can see.
What is, Visible?
600
Of the two, the frequency associated with the longer wavelength:
1.2 x 1014 Hz or 1.2 x 1018 Hz
What is, 1.2 x 1014 Hz?
Lower frequencies have longer wavelengths.
600
In this pair, the wavelength of light that has the shorter frequency:
450 nm or 700 nm
What is, 700 nm?
Longer wavelengths mean shorter frequencies.
600
The unit that is the same as Hertz.
What is 1/s or s-1 ?
Note: "s" is NOT correct.
600
The type of light that would cause the greatest jump in energy levels for an electron.
What is, Gamma?
Gamma carries the most energy and could move an electron more than less energetic forms of light.
