Joachim and Maricella are going for a romantic walk in the park after an afternoon storm. Maricella looks up in the sky and sees a rainbow
She exclaims, "How beautiful!" Joachim, being something of a science buff, might correctly say ______________________.
a) "you are just seeing the visible spectrum"
b) "that's because you are seeing all the wavelengths of light we can see from short to long"
c) "that's because different frequencies of wavelengths lead to the perception of different colors"
d) all of these things would be true if Joachim said them
ANS: D, All of these statements are correct. In viewing a rainbow, we see the visible spectrum with all the wavelengths of light, and the different wavelengths lead to the perception of different colors.
