Question
When we look at the color of light, which one is the correct answer?a. red: medium wavelengthb. yellow: long wavelengthc. green: non-visible wavelengthd. blue: short wavelengthe. purple: between long and medium wavelength
Solution
The correct answer is d. blue: short wavelength.
Here's why:
a. Red: This is incorrect. Red light actually has the longest wavelength of visible light, not medium.
b. Yellow: This is incorrect. Yellow light does not have the longest wavelength; it falls in the middle of the visible light spectrum.
c. Green: This is incorrect. Green light is visible and falls in the middle of the visible light spectrum.
d. Blue: This is correct. Blue light has a short wavelength and is near the end of the visible light spectrum.
e. Purple: This is incorrect. Purple (or violet) light has the shortest wavelength of visible light, not between long and medium.
