Actually light is a particle with very little size and the smaller ones are invisible and have small wavelenghts. By wavelenght you must interpretate how it propagates in space. Since it's small it has this characteristic. Bigger light particles have larger wavelenghts this is how they propagate in space, prob thanks to its size the propagation is less interrupted by other particles and thanks to it the wavelenght is larger.

Big light particles are invisible too, our eyes are too small for it.

People must understand that light is a particle. It's important to understand ultraviolet, x-ray, gamma ray, this used even to cure cancers.
