If the wavelengths corresponding to ultraviolet, visible and infrared radiations are given as lUV, lVIS and lIR respectively, then which of the following gives the correct relationship among these wavelengths? A. LUV < lIR < lVIS B. LUV > lVIS > lIR C. LUV > lIR > lVIS D. LUV < lVIS < lIR

[amp_mcq option1=”LUV < lIR < lVIS" option2="LUV > lVIS > lIR” option3=”LUV > lIR > lVIS” option4=”LUV < lVIS < lIR" correct="option4"]

The correct answer is D. LUV < lVIS < lIR.

Ultraviolet radiation has a wavelength of 100 to 400 nanometers, visible light has a wavelength of 400 to 700 nanometers, and infrared radiation has a wavelength of 700 to 1000 nanometers. Therefore, ultraviolet radiation has the shortest wavelength, visible light has a wavelength in the middle, and infrared radiation has the longest wavelength.

Option A is incorrect because it states that lIR < lVIS < lUV. This is not the correct order of the wavelengths.

Option B is incorrect because it states that LUV > lVIS > lIR. This is not the correct order of the wavelengths.

Option C is incorrect because it states that LUV > lIR > lVIS. This is not the correct order of the wavelengths.
