Question

a diagram of the electromagnetic spectrum is shown below. electromagnetic spectrum gamma rays x - rays ultraviolet visible light infrared waves microwaves radio waves sunscreen is a lotion used to protect skin from exposure to the sun. this sunscreen protects a persons skin from wavelengths that are longer than radio waves but shorter than x - rays. longer than x - rays but shorter than infrared waves. longer than visible light waves but shorter than radio waves. longer than microwaves but shorter than infrared waves.

Explanation:

Sunscreen protects against ultraviolet (UV) rays. On the electromagnetic spectrum, UV rays have wavelengths longer than X - rays (which are to the left of UV in the spectrum) and shorter than infrared waves (which are to the right of the visible light where UV is adjacent to).

Answer:

longer than x - rays but shorter than infrared waves.
