(2)gamma rays, ultraviolet, infrared, microwaves
(3)microwaves, gamma rays, infrared, ultraviolet
(4)infrared, microwave, ultraviolet, gamma rays

Answer: (1)

Solution

In the electromagnetic spectrum, wavelength decreases in the order radio waves > microwaves (about 1 mm - 30 cm) > infrared (about 700 nm - 1 mm) > visible > ultraviolet (about 10 - 400
