Chapter 5: Problem 5

Which of the following correctly matches the pattern in our perception of color as we move from short wavelengths to long wavelengths? a. red to orange to yellow b. yellow to orange to red c. yellow to red to orange d. orange to yellow to red

Short Answer

Expert verified
The correct option is (b) 'yellow to orange to red'.

Step by step solution

01

Understanding the Electromagnetic Spectrum and Visible Light

Visible light is a very small section of the electromagnetic spectrum, which covers a range of wavelengths. Short wavelengths correspond to the blue end of the spectrum (approximately 400nm), while long wavelengths correspond to the red end of the spectrum (approximately 700nm). As we move from short wavelengths to long wavelengths, the sequence variation of colors perceived in visible light follows the order of the rainbow or the 'ROYGBIV' system; that is 'red, orange, yellow, green, blue, indigo, violet', but we need to read it backward as we start from the short wavelength side.
02

Matching the Pattern in our Perception of Color

According to above understanding, as we move from short wavelengths to long wavelengths, the sequence in terms of colors should be from violet, blue, green, yellow, orange to red. This can be observed in natural phenomenon such as rainbows. This order is the reverse of the ROYGBIV system.
03

Selecting the Correct Option

From the provided options, only option (b) 'yellow to orange to red' falls within the described sequence. So it matches the pattern in our perception of color as we move from short wavelengths to long wavelengths.
