Reflection

Reflection. Plane (flat) mirrors. Law of Reflection. Law of reflection states that the angle of incidence is equal to the angle of reflection. θ i ° = θ r °. Definitions. 1. Incidence Ray : The ray from the source. (it is the ray from the object to the mirror.)

  1. Reflection Plane (flat) mirrors

  2. Law of Reflection Law of reflection states that the angle of incidence is equal to the angle of reflection. θi° = θr°

  3. Definitions 1. Incidence Ray : The ray from the source. (it is the ray from the object to the mirror.) 2. Normal: It is an IMAGINARY line drawn perpendicular to the surface. (It bisects the mirror.) 3. Reflected Ray: The ray reflected from the mirror.

  4. Diffuse and regular (specular) reflection Regular or specular reflection. Diffuse reflection.

  5. Diffuse and regular (specular) reflection Regular or specular reflection. Diffuse reflection.

  6. Rays off of a point object. The image as seen by the eye is:

  7. Rays off of a point object. The image as seen by the eye is:

  8. Rays off of a point object. The image as seen by the eye is:

  9. Image of an actual object. The image as seen by you is This picture shows that you actually need a mirror that is only half your length to be able to see your full image.

  10. Images between two mirrors The kaleidoscope lab show that the angle between the mirrors and the number of images are INVERSLY proportional. And the relationship is A=360º/N Here A is the angle between the mirrors and N is the # of faces.
