NGSS.HS-PS4-1

a wave in which the direction of the vibration is parallel to the direction the energy travels

Example.

sound

• Longitudinal wave
• Electromagnetic wave
• Surface wave
• Transverse wave

Term definition.

the movement of electrons from the ground state in atoms to higher orbitals and back due to the absorption and emission of energy

Example.

neon lights

• chemical reactions.

• solid materials.

• Electron Transitions

• Emission of sound .
