Physics Review Field of Vision
o o 20 20 Field of Vision Slide: Normal REMEMBER All angles are measured from the normal. Click
Angle of incidence = angle of reflection Field of Vision Slide: Draw the normal What is the angle of reflection for the ray diagram illustrated above? A) 100o B) 80o C) 50o D) 40o E) 20o Click
NOTE There are two steps in finding the field of vision. angle of incidence = angle of reflection angle of incidence = angle of reflection Step-1 Step-2 Draw a ray from the eye to the other end of the mirror. This is the reflected ray. Then, in accordance with the law of reflection, draw the incident ray. Draw a ray from the eye to one end of the mirror. This is the reflected ray. Then, in accordance with the law of reflection, draw the incident ray. Eye Field of Vision Slide: Draw the field of vision for the following systrem: Mirror Reflected ray Incident ray Normal Reflected ray Normal We can now draw the field of vision. It is the area bounded by the mirror and the two incident rays. Incident ray Field of vision (any point within this area will be seen by the observer’s eye) Click Click
Field of Vision Slide: An observer looks inside a room via a mirror as illustrated below.Which one of the four objects, A, B, C, or D, can he notsee? Room A) A B) B C) C D) D Click
Standing here, Sophie willnot be seen in the mirror. Field of Vision Slide: Total field of vision Click
Field of vision Field of vision Field of Vision Slide: In which of the following is the image of the object not seen by the observer? Field of vision Field of vision The field of vision is the space between the twoincident rays. O = Observer Any object within the field of vision will be reflected in the mirror. This object isoutside thefield of vision. Click
Observer Field of view of side-view mirror Field of view of rear-view mirror Object C is in bothfields of view. Field of Vision Slide: According to the diagram below, which object (A, B, C or D)can be seen by the observer in both the rear-view andthe side-view mirror? A) A B) B C) C D) D Click
The End … and good luck!
