light
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.
When light hits an object, it can be absorbed (taken in by the object), reflected (bounced off the object), transmitted (pass through the object), or refracted (bent as it passes through the object).
When light travels through a pair of eyeglasses, they are refracted (bent) by the lenses to correct vision problems such as nearsightedness or farsightedness. The lenses in the eyeglasses help to focus light properly onto the retina at the back of the eye, allowing for clearer vision.
When light strikes a transparent object, it can be transmitted through the object, reflected off its surface, or refracted (bent) as it passes through. The behavior of light will depend on the angle at which it strikes the object and the material properties of the object.
Refraction is the change in direction caused by a speed differential as light travels through different mediums, or temperature/pressure gradients. Reflection is light directly hitting an object and exiting at the same angle at which it hit.
When light hits the surface of an object at an angle, it can be reflected (bounced off), refracted (bent), or absorbed by the object. The amount of light that is reflected or refracted depends on the surface properties of the object, such as smoothness and transparency.
When light moves from air to oil, the refracted ray is bent towards the normal. This is because light travels at different speeds in different mediums, causing it to change direction at the boundary between the two mediums.
A prism is a transparent object that allows light to bend. When light passes through a prism, it is refracted or bent, causing it to separate into its constituent colors due to the different wavelengths of light.
When light rays are bent, they are called refracted. Refraction occurs when light passes through different mediums of different optical densities, causing the light rays to change direction.
White light is separated into its component colors when it passes through a prism due to the phenomenon of refraction. Each color has a different wavelength and is bent by a different amount, resulting in a spectrum of colors ranging from red to violet. This separation of colors is known as dispersion.
It's a tricky question, and I am answering from the point of view of an interested layman, not a physicist. Light travels on a straight path through space. The interesting reality is that the space around gravitational fields bends.Light travels in a straight path through bent space. Also, light can be transmitted through optical fibers in communications systems, and the light follows the fiber through whatever bends are put into it.
When light travels through a prism, it is bent or refracted as it passes from air into the prism and then again as it exits the prism. Different colors of light are refracted by different amounts due to their different wavelengths, causing them to separate. This separation creates a rainbow effect known as dispersion.
