Answer:
longer/less
Explanation:
In moving from left to right on the electromagnetic diagram, the wavelength becomes longer and the energy lessens.
The electromagnetic diagram presents a spectrum of radiation.
- The left most wave is the most energetic and the right most radiation is the least energetic.
- Also, as energy decreases from left to right, the frequency of the wave also decreases.
- But the wavelength increases or becomes longer.
