Need not be opaque to other wavelength ranges. A thin metal sheet is opaque to visible light, but not to x-rays.
shadow formed on the other side of transparent material
light can travel through anything. Light here means electromagnetic radiation, not just visible light. Visible light cannot go through anything opaque, such as metal sheets. Other types of electromagnetic radiation, like X-rays, can pass through almost anything. If you want the name ofa material where no EM radiation can pass through, it's thick lead sheet.
OPAQUE is the word that describes an object or substance that blocks light (or other energy form). TRANSLUCENT describes objects that allow transmission of light, but scatter it from the original form or direction. TRANSPARENT describes objects that allow the passage of light, usually optically clear substances such as glass.

Refraction is the phenomenon which allows light to pass from one medium into the other. But opaque object will not allow light to pass through. So refraction becomes impossible in case of opaque objects.
shadow formed on the other side of transparent material
Clear and transparent are the synonymous. A transparent material allows light to pass through. Opaque, on the other hand, do not allow light to pass through

A converging (convex) lens will produce a shadow with the focal point in the center.
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
Some gasses are opaque to certain wavelengths of the electromagnetic spectrum. Ozone O3 is opaque to UV rays and blocks them. Other gasses are opaque to other wavelengths.
wood Think of any material that you cannot see through. Steel, Concrete, Granite,... These are opaque: Light does not pass from one side to the other. Examples of materials that are not opaque: Water, Glass, Air [a mixture of gases]

Since the object appears violet to your eye, it must be that violet light is the wavelength most efficiently reflected ... least efficiently absorbed ... by the object. To a greater or lesser degree, all wavelengths that are not reflected from the object are absorbed by it.
An opaque material has a more dense pattern of molecules. Opaque materials do not allow light to pass through them. so then that means you could not see any light through the construction paper. because it is a kind of solid and it is hard to see through a unclear solid.
An opaque object absorbs all the light that hits it. That's whythere's never any light left to come out of the other side.
