Convex mirror: A curved mirror whose reflective side is on the outside of the curve. Mirrors can be curved as well as flat. One ...

convention allows the use of a single equation to locate images and objects for both types of mirrors. Our study of mirrors will ...

Concave spherical mirror: f = r/2 Convex spherical mirror: f = ír/2 f = focal length r = distance to center of curvature What is ...

The parabolic design is used not just for visible light but for other forms of electromagnetic radiation, like radio waves, as w ...

To locate the image, we start with three rays emanating from the top of the object: in this case, the top of the penguin’s head. ...

Now that the three rays have been drawn separately, we draw them together in Concept 5. They converge at the head of the image. ...

Ray 3 starts at C. It passes by the penguin’s head and reflects back through C. In Concept 5, you see all three rays in the same ...

Ray 1. Ray 1 is incident parallel to the principal axis. If we extend the reflected component of this ray backward through the m ...

Finally, in Concept 6, we show the image as determined by the convergence point of the virtual rays. The image formed is upright ...

what people ordinarily think of as “magnified.” Now, on to the equations. The mirror equations are very useful for designing equ ...

What is the distance to the object? di = í2.0 m, f = í6.0 m do = 3.0 m What is the magnification? ho = +0.60 m, hi = í 0.40 m m ...

31.16 - Interactive checkpoint: mirror equations A frog sits in front of a convex spherical mirror. The mirror produces an image ...

31.19 - Summary Reflection occurs when light bounces back from a surface, rather than passing through it or being absorbed. Refl ...
