Which term is the angle between the normal and a reflected ray of light?

• A. Appraisal
• B. Angle of reflection
• C. Alluvial deposit
• D. Abrasion

Answer: (B)

The angle between the normal and the reflected ray is called the angle of reflection. The normal is the line perpendicular to the surface, and the reflected ray forms this angle with the normal. According to the law of reflection, the angle of incidence (the angle between the incoming ray and the normal) equals the angle of reflection. The other terms—appraisal, alluvial deposit, and abrasion—are unrelated to light behavior, so they don’t describe this concept.
