Reflection Flashcards
1
Q
1st law of reflection
A
the incident ray and the reflected ray and the normal at the point of incidence all fall in the same plane called the plane of incidence.
2
Q
2nd law of reflection
A
the angle of incidence is equal to the angle of reflection
3
Q
principle of reversibility
A
reflection of light is reversible, meaning the incident ray and the reflected ray can switch places without violating the first two laws.
4
Q
SPECULAR reflection
A
occurs on a smooth surface where a parallel beam of light is reflected in one specific direction.
5
Q
DIFFUSE reflection
A
occurs on a rough surface where a parallel beam of light is reflected in random directions.
