Question

​Regarding light and vision, which of the following statements is FALSE?

a. ​X-rays, ultraviolet waves, and radio waves are portions of the electromagnetic radiation spectrum that humans cannot "see."
b. ​Human vision perceives wavelengths of light between approximately 300 and 750 nanometers.
c. ​Of the colors, red has the shortest wavelength.
d. ​Light is physical energy in the form of electromagnetic radiation.

Answer 1

Of the colors, red has the shortest wavelength is FALSE.

Step-by-step explanation:

The statement that is FALSE is c. Of the colors, red has the shortest wavelength.

The colors of visible light have different wavelengths, with red having a longer wavelength than other colors such as purple or blue. The spectrum of visible light ranges from approximately 400 to 700 nanometers, with red light at the longer end of the spectrum.

X-rays, ultraviolet waves, and radio waves are indeed portions of the electromagnetic spectrum that humans cannot see, as stated in option a. Light is physical energy in the form of electromagnetic radiation, as stated in option d.
