Final answer:
The statement is false. Construction Type III requires exterior walls to be non-combustible, but interior building elements are subject to fire resistance requirements, not any material. Other IBC construction types also allow for a mix of materials.
Step-by-step explanation:
The statement that Construction Type III is the only type that allows construction of exterior walls of non-combustible materials and interior building elements of any material permitted by the International Building Code (IBC) is false. In fact, Type III construction typically requires that exterior walls be of non-combustible materials, but it does not permit interior building elements to be of any material. Other construction types under the IBC also allow for a mix of materials for different building elements, with varying levels of fire resistance requirements. Construction types are defined by the IBC to ensure safety, taking into account factors such as fire resistance and the building's materials.
The statement in question is false. The two types of interference are actually constructive and destructive interference. Constructive interference occurs when waves combine to produce a larger amplitude, resulting in a wave with increased intensity. Destructive interference, on the other hand, occurs when waves combine to produce a smaller amplitude or cancel each other out, resulting in a wave with decreased intensity.
