Waves & Electromagnetic spectrum

What is the relationship between amplitude and the energy of a wave

• There is an indirect or opposite relationship between amplitude and energy of a wave

• There is a direct or same direction relationship between amplitude and energy of a wave

• There is no relationship between amplitude and energy of a wave

Electromagnetic waves transfer energy and

• need a medium to travel

• need mediums that are solids, liquids an gases

• do not need a medium to travel

When a wave interacts with a surface, four interactions can occur.

• They are period, frequency, amplitude, and equilibrium.

• They are oscillations, mediums, compressions, and rarefactions.

• They are matter, energy, wave speed, and wave cycling.

• They are reflection, refraction, absorption, and diffraction
