Ok so the question I was thinking to myself was, If sound waves can travel through walls why can't light.
Some frequencies of light can pass through walls such as infra red (heat) and x rays (extremely high frequency). As with sound, the thickness of the
wall and the strength of the light/sound makes a difference as to if it can pass through or not.
I just can't see how a wall could have a wavelength similar to light.
Each specific colour is at a specific wavelength. The fact that you can see a colour indicates that you can see the wall. The colour of the wall
alters the lights photons wavelength as it bounces of the wall and enters your eye. It is pretty tricky how different compounds alter the wavelengths
of the photons that bounce of them. While it may not always be easy to understand, there is always a reason why.
the problem i have with that is that a photon is both partice and wave
A lot of people and science in general is still having a problem with it. With a photon being mass less is part of it, according to the theory of
relativity it should also be frozen in time travelling at the speed of light. But different substances to alter the speed that light travels. It does
