No it can not.
No, visible light and infrared light do not pass through the same types of materials. Visible light can pass through materials like glass and water, while infrared light can pass through materials like plastic and some fabrics.
This question needs to be rewritten, it is not clear. Possible answer: reflection. Those that do enter the block, will be refracted, if the glass does not have the same index of refraction as the substance around it.
If the refractive index of glass is the same as that of air, then there would be no refraction of light as it passes from air to glass. This would result in light passing through the interface without bending, leading to minimal distortion or deviation of the light rays.
No, such a transparent metal is not possible. Metals are a conductor of electricity. As a result of this, electromagnetic waves of the wavelength of light cannot penetrate it.
Glass is a good transmitter of sound, allowing it to pass through easily. However, it does not conduct sound in the same way that a metal would conduct electricity, for example. Instead, glass allows sound waves to move through it, making it possible to hear sounds on the other side.
No, you cannot go through security twice with the same boarding pass.
A glass box reflects light due to the smooth surface of its material. When light hits the glass, it bounces off at the same angle it came in, creating a reflection. The transparency of the glass allows some light to pass through, while the rest is reflected back.
Glass is transparent, which allows light to pass through it. When light hits the glass at a certain angle, some of it is reflected back to our eyes, allowing us to see our image. The rest of the light passes through the glass, enabling us to see through it.
In short, your initial assumptions are flawed. Every different chemical compound will allow light of some wavelengths to pass through, and will absorb some other wavelengths. In the case of glass and many acrylic polymers, they both appear to be clear because most of the light in the visible spectrum passes through. It is not generally true that glass allows infrared light to pass through, nor is it generally true that acrylic polymers will allow ultraviolet light to pass through. The infrared light absorbed by both acrylic and glass heats up the material by causing bending, stretching, and twisting of mmolecular bonds. The ultraviolet light absorbed by these materials generally causes ionization.

Electromagnetic waves such as light can pass through material medium such as water, glass etc and at the same time it could pass through vacuum ie a medium of free space.
Clouds, some glass in vases and cups/glasses.
