Radio waves have wavelengths greater than 1 centimeter.

Explanation:
Radio waves are the part of the electromagnetic spectrum with wavelengths longer than about 1 centimeter, while shorter wavelengths fall into microwaves. This practical boundary means signals used for radio communication—AM/FM, wireless, etc.—lie in the region longer than 1 cm. So, the statement that radio waves have wavelengths greater than 1 centimeter aligns with the common convention, making it true. Some texts vary the exact cutoff a bit (around 1 mm), but the 1 cm boundary is widely used in introductory contexts.
