Answer:
longer/less
Step-by-step explanation:
In moving from left to right on the periodic table, electromagnetic waves have longer wavelength and less energy.
The electromagnetic radiation diagram is made up of electromagnetic waves.
- From left to right, the energy of the wave decreases.
- Waves at the left most edge have the highest energy.
- As we move rightward, the wavelength also becomes longer.
- The frequency also reduces.
- Wavelength and energy are inversely proportional.
