QUESTION 8
Some commonly used wavelengths of EM radiation are: 850 nm (infrared security cameras), 630 nm (red LED light), 12.24
cm (microwave oven), 254 nm (ultraviolet light based sterilization), and 1.00 pm (generic gamma ray possibly useful for
radiation therapy). Rank these by the frequency, from highest to lowest
nm nanometer (10^-9)
pm picometer (10^-12)
=
