Question

Light has what range of wavelength?       

A. 700 nm to 400 nm  
B. 400 nm to 10 nm  
C. 0.3 nm to 0.001 nm  
D. 10 nm to 0.01 nm

Answer 1

Answer: 700 nm to 400 nm

Step-by-step explanation:

in my textbook it states "The wavelengths of light waves are from about 700 nm to 400 nm. This is about one hundredth the width of a human hair."

Answer 2

I think it's A even though I think it's 400 to 700 but maybe I'm just thinking backwards but anyways it's probably A
Hope I helped in some way
