What is another word for normal-incidence wave?
Pronunciation: [nˈɔːmə͡lˈɪnsɪdəns wˈe͡ɪv] (IPA) 
A normal-incidence wave refers to the wave that hits a surface at a perpendicular angle. It is also known as a perpendicular wave or a normal wave. Other synonyms for a normal-incidence wave are orthogonal wave, transverse wave, right-angle wave, and 90-degree wave. These waves are an important concept in physics, particularly in optics, where they are used to describe the behavior of light waves. Normal incidence waves are also used in the study of sound waves, where they are used to describe the reflection and absorption of sound waves at surfaces. Understanding the different terms that refer to normal incidence waves is essential in effectively communicating concepts within the field of physics.
