The speed of light is not affected by the density of the medium. Its the path of the light that is affected . Phenomenon like reflection or refraction take place when the light goes to different medium
When light travels through anything that is not a vacuum, it will usually slow down.
nothing can do but if it is a laser means the solid will cut into 2 pices
The speed of light decreases when it travels from air into glass because the glass has a higher refractive index than air. This causes the light to slow down as it moves through the denser medium.
If light passes into a material where the speed of light is faster, it will bend away from the boundary between the two materials. This occurs because light travels more slowly in denser materials, and when it exits into a less dense medium (where it travels faster), it refracts away from the normal line at the boundary. This behavior is described by Snell's law.
Nothing happens to light waves at all. UNLESS the two materials happen to be right next to each other AND the light tries to cross FROM one INTO the other one. Then things get very interesting.
Light can travel through various materials such as air, water, glass, and even some types of plastics. The speed of light can vary depending on the medium it is traveling through, with the speed being fastest in a vacuum.
They disperse.
opaque material: some light will get reflected and some will get absorbed transparent material: light will go though it
Light travels in a straight line through a vacuum or transparent materials.
Yes, through some materials. It certainly travels through air, and you may have noticed that it travels through water and glass.Yes, through some materials.

the light travels though the prism and is reflected on an object and the light is to go though all side/faces of the prism and the light is to change colorTo make this more clear: The light goes through and separates into different colors of the rainbow.
Optical Density. Which often is caused by normal density.
it travels at c (speed of light in a vacuum)
Light travels in a straight line, at a constant speed in a vacuum, and can be reflected, refracted, or absorbed when it encounters different materials or surfaces.
Yes. The more dense the material the slower light travels. Light travels the slowest in diamond at about a third of its normal speed of 300 000 km /s in a vacuum.
Opaque materials.
Light travels through the air. Light is a big mystery because it seems to be both a wave and a particle. Light will just travel through anything that doesn't block it.
