UV rays.
Types of bed vary some by construction, but all use flourescent lights which emit UVA rays.
No, because Segment Construction Postulate may be use in any rays,there is exactly one point at a given distance from the end of the ray and in Segment Addition Postulate is is you may add only the Lines.
Greenhouses typically are made of materials that filter out some of the UV rays, but not all. While they can reduce the amount of UV radiation entering the greenhouse, some UV rays may still pass through. It's important to consider the materials used in the construction of the greenhouse to determine its UV-blocking capabilities.
Gamma rays can be used for sterilizing medical equipment and food products, as well as in the treatment of certain materials to improve their properties, such as polymers and semiconductors. Additionally, gamma rays are used in industrial radiography to inspect welded structures and other manufactured components for defects.
A virtual image is so named because there is no actual light rays originating from the image. Rather, the image is a construction of the human nervous system that retraces diverging light rays straight back to a single point of origin without regard of any lenses.

Gamma rays.
Materials with high atomic numbers, such as lead or concrete, are effective at shielding against gamma rays due to their ability to absorb and scatter the radiation. Thick layers of these materials are commonly used in the construction of shielding barriers to protect against gamma ray exposure. Lead is often preferred for its high density and effectiveness in blocking gamma rays.
marginal rays are those rays which are near the rim of lens and axial rays are those rays which are formed near the axis
Yes, X-rays and gamma rays have higher frequencies than ultraviolet rays.
Cathode rays generate x-rays and gamma rays are electromagnetic radiation. Gamma rays have very high penetration power.
