Question 1

Electromagnetic waves are crucial in various biological and technological processes, where they function to transfer energy from a source to an absorber. For instance, visible light transfers energy from the Sun to the chlorophyll in plant leaves, driving photosynthesis and raising its internal chemical energy.

Describe examples of two other distinct regions of the electromagnetic spectrum transferring energy. For each wave, your description must identify:

  • the specific electromagnetic wave, and
  • how or where the energy is absorbed, and the resulting physical, biological, or chemical effect.
