I believe that light is considered to be both waves and also particles. My understanding is the particles room physical objects. If that is true, just how is irradiate able to travel v glass? Is it just the irradiate waves that travel through glass or have the right to the particles likewise penetrate glass?


The very first thing is that any type of solid object the looks solid to us is in reality has substantial amount of space in it...

Even in an atom, the cell nucleus of the atom is around a hundreds thousandth the the dimension of the actual atom. For this reason there"s immense quantities of empty an are only containing electrons, i beg your pardon are even smaller 보다 the nuclei, therefore there"s lots and lots of room for points to travel through, as long as that doesn"t interact with the nuclei or electrons.

A light tide is in reality quite large compared come the dimension of an atom. It"s a quantum mechanical object - it"s type of a particle, yet it"s kind of a wave. You can think of the as tide which only arrives in particles - not really something through which we have a take care of on.


It"s a lot easier to think the it together a tide in the circumstance. The only method to prevent a wave is through something which will certainly actually absorb that or scatter it, and in something like glass there"s simply nothing over there which will absorb or to scatter it. So it simply carries on walking in a straight line.

Addendum for clarity:

Light is an electromagntic wave; that way that the comprises a an altering electric field, i beg your pardon produces a changing magnetic field, i beg your pardon produces a an altering electric field and also so on... This is exactly how the irradiate propagates v space.

When light rays communicate with an entity, prefer a piece of glass, the electromagnetic wave causes the electron clouds in the product to vibrate; as the electron clouds vibrate, castle regenerate the wave. This wake up in a succession of "ripples" as the light passes through the object. Because this procedure takes time, that"s why light slows under slightly in optically an ext dense materials like glass.

Different color of light have different frequencies; light the is visible to united state passes through glass since the plan of the atoms in glass means that they deserve to sustain the ripple effect described above at those frequencies, therefore light can pass through.

But other materals, through a different configuration of atom in the decision structure, cannot allow light come propagate and also instead absorb the energy. A good example that this is an X-ray. It will go right through a human body mostly unchanged, yet the command apron worn through the radiographer stop it in its tracks.
