Question

question 11
which of the following puts the wavelengths of light in order from shortest to longest?
a green→violet→yellow→red
b yellow→green→red→violet
c violet→green→yellow→red
d red→yellow→green→violet
e violet→red→yellow→green
question 12
a particle of light energy is called a:
a lumen.
b spectrum.
c photon.
d wavelength.
e nanometer.

Explanation:

• For Question 11: In the visible - light spectrum, violet has the shortest wavelength and red has the longest, with green and yellow in between in that order.
• For Question 12: A particle of light energy is defined as a photon. A lumen is a unit of luminous flux, a spectrum is a range of wavelengths, a wavelength is the distance between wave crests, and a nanometer is a unit of length for measuring wavelengths.

Answer:

Question 11: C. violet→green→yellow→red
Question 12: C. photon
