yes,it will slow down
No, when light passes into a denser material, it bends toward the normal. This phenomenon is known as refraction.
Light will bend toward the normal, or perpendicular line, when passing from a less dense to a denser material. This is known as refraction.
When light passes through dense materials, such as glass or water, it is slowed down due to the interactions with the atoms in the material. This slowing down causes the light to bend or refract as it passes through the material. The denser the material, the more the light is slowed down and bent.
When light passes into a denser substance, it undergoes refraction - its direction changes because the speed of light is slower in the denser substance. The light ray bends towards the normal (an imaginary line perpendicular to the surface) at the point of entry into the denser substance.
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.
A material with a high refractive index, such as glass or acrylic, will typically give straight lines when light passes through it. This is because light rays passing through denser materials tend to refract less and maintain their direction more effectively.
When a ray of light passes from an optically denser medium to a rarer medium, it bends away from the normal. This phenomenon is known as refraction. The speed of light changes as it moves from one medium to another, causing the change in direction.

When light travels from a less dense medium to a denser medium, it bends towards the normal. This is because light slows down in a denser medium, causing it to change direction. When light travels from a denser medium to a less dense medium, it bends away from the normal as it speeds up in the less dense medium.
The density of matter affects the propagation of light waves by changing the speed at which light travels through the material. Light travels slower in denser materials, causing it to bend or refract as it passes from one medium to another.
Opaque Material That Light Passes Less
The Ray of light bends toward the normal line. The reason is the light in the more dense region has slower speed. The relationship is given by the Law of Signs:sin(incident angel)/incident speed = sin(refracted angle)/dense speedSin(I)/vi = Sin(dense)/vd
