Answer: Geometrical optics
Card 2
Question: How does ray optics treat light?
Answer: As rays traveling in straight lines
Card 3
Question: When is the ray model an excellent approximation for light?
Answer: When the wavelength of light is much smaller than the objects it interacts with
Card 4
Question: What is the most basic principle of ray optics?
Answer: Rectilinear propagation of light
Card 5
Question: What does the principle of rectilinear propagation of light state?
Answer: Light travels in straight lines in a uniform medium
Card 6
Question: What phenomenon occurs when light rays strike a surface and bounce back into the same medium?
Answer: Reflection
Card 7
Question: What are the two parts of the Law of Reflection?
Answer: 1. The incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane. 2. The angle of incidence (
Card 8
Question: How are the angle of incidence and angle of reflection measured?
Answer: With respect to the normal, an imaginary line perpendicular to the surface at the point where the light ray strikes.
Card 9
Question: What type of images do plane mirrors form?
Answer: Virtual images that appear to be behind the mirror, are upright, and are the same size as the object, with the image distance equal to the object dist
