Which range of electromagnetic radiation wavelengths is most readily detected by the human eye?

• A. 10 nm to 100 nm
• B. 400 nm to 700 nm
• C. 1 nm to 10 nm
• D. 700 nm to 1200 nm

Answer: (B)

Verified step by step guidance

1. Understand that the human eye detects visible light, which is a specific range within the electromagnetic spectrum.
2. Recall that electromagnetic radiation includes various types such as gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, and radio waves, each with different wavelength ranges.
3. Identify the wavelength range corresponding to visible light, which is the portion of the spectrum the human eye can detect.
4. Note that visible light wavelengths range approximately from 400 nm (violet) to 700 nm (red).
5. Compare the given options to this range and recognize that 400 nm to 700 nm is the correct range for wavelengths most readily detected by the human eye.
