Question

Which statement best describes wavelengths of sunlight that are longer than 700 nanometers? These wavelengths form the infrared part of the spectrum. These wavelengths form the ultraviolet light of the spectrum. These wavelengths are shorter than the wavelengths of visible light. These wavelengths are part of the visible light spectrum.

Answer 1

Answer: These wavelengths are longer than wavelength of visible light. These wavelengths form the infra-red part of the spectrum.Explanation:

These wavelengths form the infra-red part of the spectrum.

Step-by-step explanation:

Solar spectrum has lies in three parts of the electromagnetic spectrum - Ultraviolet, visible and infra-red.

Visible light lies from 400 nm to 700 nm.

Ultraviolet region precedes visible spectrum and has shorter wavelength than it.

Beyond visible spectrum, infrared part of the spectrum starts and has longer wavelength than it.

Answer 2

Option A is the appropriate approach.

Step-by-step explanation:

• Throughout reality, the sun produces light across all colors, but rather because yellow would be the strongest wavelength of the sun, that's color that only the image recognizes through our naked eyes, although you can never glance up towards the sky.
• The infrared portion including its spectrum is created by some of these wavelengths.

The other options offered are not relevant to the situation described. So, the solution here is just the right choice.
