This may not be what you are going for, but as worded the question seems to be asking about what could be called a transparency, slide, or frame. Some camera films are made so that they can be developed and then used in a slide presentation; the actual developed film is put into a projector, and light from the projector passes through the slide, or transparency, to reproduce the image on a screen. In movies that are actually made with film rather than digitally, each separate image on the film is called a frame.
Refraction
Diffraction.
It is called "transparent".
The passage of light through an object is called transmission. This process occurs when light passes through a material without being absorbed or reflected.
You will see what some people call a rainbow, the differing refraction of light frequencies
The displaced image of an object due to the bending of light rays is known as a virtual image. This type of image cannot be projected onto a screen and is formed where light appears to diverge from after passing through a lens or mirror.
Objects that allow most light to pass through are described as transparent. In contrast, translucent objects allow some light to pass through, but don't let you see objects. Opaque objects allow no light to pass through.
The bending of light as it passes through a slit in cardboard is called diffraction. This phenomenon occurs when light waves encounter an obstacle or aperture, causing them to spread out and interfere with each other. Diffraction is a property of waves and occurs due to the wave nature of light.
Nothing comes through. A red light emits no blue light, and a blue filter allows only blue light to pass ... that's why when you look at it, you say to yourself "Hey! That filter looks blue. I'll call it a 'blue filter'."
When sunlight passes through raindrops, the drops scatter the light which then appears to the onlooker to form a band of colors in the sky - or as we call it, a rainbow.
