Question

6. Which color of light has a longer wavelength: red or green?

Answer 1

Red

Step-by-step explanation:

The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red.

So red has a longer wavelength than green.

Answer 2

Answer is Red

All the colors we see are combinations of red, green, and blue light. Visible light may be a tiny part of the
electromagnetic spectrum, but there are still many variations of wavelengths. We see these variations as colors. On one end of the spectrum is red light, with the longest wavelength.
