Question

which type of emr has the 2nd shortest wavelength (λ)?
○ infrared
○ x - rays
○ microwaves
○ visible light
○ radiowaves
○ ultraviolet
○ gamma rays

Explanation:

The electromagnetic - radiation (EMR) spectrum, from longest to shortest wavelength, is: radiowaves, microwaves, infrared, visible light, ultraviolet, x - rays, gamma rays. So the type with the second - shortest wavelength is x - rays.

Answer:

x - rays
