Question

Consider these colors of light: yellow, blue, and red.

Put these light waves in order according to wavelength, from shortest wavelength to longest wavelength.

a) Blue, yellow, red.

b) Yellow, blue, red.

c) Red, yellow, blue.

d) Red, blue, yellow.

Answer 1

The correct order of the colors blue, yellow, and red by wavelength from shortest to longest is blue, yellow, red. Since wavelength and frequency are inversely related, the order by frequency from lowest to highest is red, yellow, blue. Therefore, the correct answer is option d).

Step-by-step explanation:

The question involves organizing colors of light based on their wavelength and frequency. To order the colors yellow, blue, and red by wavelength from shortest to longest, we use the mnemonic ROY G BIV, which stands for the colors of the visible light spectrum, with red having the longest wavelength and violet the shortest. Using this, we know that blue light has a shorter wavelength compared to yellow, and yellow has a shorter wavelength compared to red.

Therefore, for Part A, the correct order from shortest to longest wavelength is: blue, yellow, red.

Since frequency and wavelength are inversely related for electromagnetic radiation, the order for frequency from lowest to highest would be the opposite: red, yellow, blue.

Hence, the correct answer from the options provided is d): wavelength: blue, yellow, red; frequency: red, yellow, blue.
