Final answer:
The types of light radiation harmful to buildings are ultraviolet, infrared, and, in extreme situations, x-ray and gamma radiation. These can cause damage such as warping materials, fading paint, and even structural damage.
Step-by-step explanation:
In the context of physics, the forms of light radiation that are harmful to buildings generally include ultraviolet (UV) radiation, infrared (IR) radiation, and in extreme cases, x-ray and gamma radiation. Ultraviolet radiation from the sun can fade paintwork and finishes on buildings, deteriorate certain materials like plastics, and harm outer finishes. Infrared radiation, which is essentially heat, can warp or damage materials when intensely concentrated, such as in a fire. X-ray and gamma radiation are really only concerns in certain industrial or scientific environments, due to their ability to ionize materials and cause structural damage over time.
