    Hi Hoontaek,
    if the wavelength exceeds the size of the particle, the interaction is weaker or not present at all. The molecule or particle is only sensed properly if the relation between ‘target’ size and wavelength is appropriate.

    Hi, I have a question.

    In the box “why is the sky blue?”, it says that “While longer wavelengths simply pass through the particles, shorter wavelengths exhibit a greater probability of being scattered.” My question about this sentence. Why do longer wavelengths just pass through, while shorter ones cannot and interact with particles in the air?
