Question

a) the color intensity of light waves
b) number of waves passing a point per second
c) total energy of a single wave
d) distance between wave peaks

1. why do dark - colored objects absorb radiant energy faster than light - colored objects?

a) dark colors have more molecular density
b) dark surfaces have more heat - trapping molecules
c) dark colors have different atomic structures
d) dark surfaces have more energy - absorbing electrons

Explanation:

For the first part, the number of waves passing a point per second is the definition of frequency. For the second part, dark - colored objects absorb radiant energy faster because they have more energy - absorbing electrons which can take in photons of light and convert them into other forms of energy like heat.

Answer:

1. B. Number of waves passing a point per second
2. D. Dark surfaces have more energy - absorbing electrons
