Question

An object appears green. what wavelength of visible light is your eye detecting? group of answer choices

a. 440 – 485 nm
b. 510 – 565 nm
c. 625 – 740 nm
d. 380 – 440 nm

Answer 1

The correct wavelength of visible light detected by the eye when an object appears green is within the range of 510 – 565 nm. Option number b is correct.

Step-by-step explanation:

An object appears green because it reflects light in the wavelength range that corresponds to green. In the visible spectrum, which lies between 380 nm and 740 nm, the specific wavelengths for green color are typically around 510 – 565 nm.

When white light hits an object, the object absorbs certain wavelengths and reflects others; a green object absorbs wavelengths outside of the 510 – 565 nm range and reflects those within it, making it appear green to our eyes. Therefore, the correct answer to the question 'An object appears green. What wavelength of visible light is your eye detecting?' is option b. 510 – 565 nm.
