	List I		List II
A	Visible Light	1	0.1 to 10 nm
B	Ultraviolet	2	400 to 700 nm
C	X-Rays	3	Longer than 740 nm
D	Infrared	4	100 to 400 nm
		5	0.1 nm

• A. A- 1, B- 3, C- 4, D- 5
• B. A- 3, B- 2, C- 1, D- 5
• C. A- 4, B- 3, C- 2, D- 1
• D. A- 2, B- 4, C- 1, D- 3
• E. A- 5, B- 4, C- 3, D- 2

Answer 1

The correct option is D A- 2, B- 4, C- 1, D- 3

• The visible spectrum is the range of wavelengths of electromagnetic radiation that is visible to the human eye and falls between 390/400 to 700 nm.
  
• Birds and bees can detect through ultraviolet light - 300–400 nm, X-rays fall into the 0.1 - 10nm wavelength spectrum and infrared falls between 10 nm to above 700 nm wavelength.
  Hence, option D is correct.
