This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Dental
A material which partially transmits light & partially scatters it: 
Select and explain. 
A. Reflector, B. Translucent, C. Transparent, D. Opaque
B: Translucent
Answer: B: Translucent 
Explanation: When light passes through a transparent medium such as plain glass, it is neither reﬂected nor absorbed but totally transmitted through.  
A translucent material, on the other hand, gains its transmitted color by the resultant spectrum it transmits. As a beam of light passes through a translucent material such as glass, it can be changed by adding ﬁne particles that scatter the light giving a milky appearance.
