Light can go through straight tubes because there are no obstacles to block its path. In contrast, in bent tubes, the surfaces reflect or scatter light, causing it to bounce around rather than travel straight through. This bending of light prevents it from passing through the tubes and results in internal reflection.
You can't see an object through a bent pipe because light does not travel in straight lines when passing through the bent pipe. The light rays are refracted as they enter the pipe, causing the object to appear distorted or blocked from view due to the curve of the pipe.
Light travels in straight lines, which prevents us from seeing a source of light through a bent tube. When light encounters a bend, it gets reflected or scattered, making it impossible for us to directly see the light source.
Yes, light can be bent or refracted when it passes from one medium to another with a different optical density, causing the light waves to change direction. This phenomenon is commonly seen when light passes through lenses or water.
The light will pass straight through the glass block if shone perpendicularly, without getting refracted or bent due to the change in medium.
Light rays travel in a straight line unless they are refracted or reflected by a medium. This straight path is known as rectilinear propagation. Light rays can also be bent when passing through different mediums with varying optical densities.

Light always travels in a straight line with respect to space-time. If it appears to the observer that the light beam has bent it can only be concluded that space-time is bent.

Light travels in a straight line, as long as it is propagating through a constant medium. In space, space is pretty much empty, so the light travels in a straight line. When light passes into a different medium, such as from space into air or from air into glass, the light is bent or "refracted". You can see this for yourself; poke a straight stick into a pond or pool of water. Look at the stick. The light reflected from the stick to your eye allows you to see the stick, but the light from the part of the stick that's in the water is bent - so it appears as if the stick itself is bent. The light from the stick through the water is refracted differently than the light from the stick through the air. The greater the density of the material, the more the light will be refracted. To magnify light, we need to gather in a lot of light and bend it into a smaller area. We can use curved glass surfaces (or curved mirrors) to bend the light into a smaller area, which magnifies the light. The more dense the glass is, the more the light will be bent into a smaller area.

light
In a sense, light does not bend. Light sometimes passes through space (or space-time) that is warped or bent because of a nearby object having very strong gravity. The light passes through this space in what (from the light's point of view) is a straight line. To other observers the light may appear to have followed a bent path. So gravity warps space-time, and light appears to bend as it travels through this warped space-time. The light isn't doing anything except following what is a completely natural path through space.
Refraction
When the speed of light in the two media is not the same.
When white light passes through a prism, blue light is bent the most followed by violet, while red light is bent the least. This separation of colors is known as dispersion.
