Question

Do smells have “frequencies” in the same way that lights and sounds have?

In: Biology

Answer 1

I mean almost. Sounds travel in waves that have contracted areas and expanded areas so not uniform. Lights are a constant amount but as it expands it spreads to a larger areas it’s strength gets more spread out. Smells are aromatics that diffuse through the air. If it were perfect diffusion then it would diffuse more like light but slower but not like sound. Smell would not have frequencies.
