Question

As the wavelength of electromagnetic radiation increases _______.

Answer 1

'frequency' is less: it decreases.

Step-by-step explanation:

Answer 2

The wider the waves are spread out, the longer it takes for each cycle to pass a given point. It's this—how FREQUENTLY waves pass a point—that determines the value of 'frequency'. If they are going by less frequently past that point, then the 'frequency' is less: it decreases.
