Answer: radio waves, microwaves, infrared waves.

Explanation:

Electromagnetic spectrum increases in wavelength and decreases with frequency in the following order

Gamma ray, X ray, Ultraviolet rays, Visible light, Infrared rays, Radio waves.

Since 397nm is greater than the value of visible spectrum, this shows that radio waves, microwaves and infrared wave falls in the spectrums of the wavelength value.
