Mirrors•Smooth surfaces that reflect light
waves
![Page 4: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/4.jpg)
Mirrors•Mirrors have been used for thousands
of years by polishing metal
![Page 5: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/5.jpg)
Mirrors•Mirrors producing sharp
& well defined images were developed by Jean
Foucault in 1857
![Page 6: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/6.jpg)
Mirrors•Jean Foucault developed
a method to coat glass with silver making excellent mirrors

Object•The source of the
spreading light waves being
observed
![Page 8: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/8.jpg)
Image•A reproduction of an
object observed through lenses or
mirrors
![Page 9: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/9.jpg)
Image•When you look into a
mirror, you see an image of yourself
![Page 10: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/10.jpg)
Plane Mirror•Mirrors on smooth flat
surfaces that give regular reflection and
good images
![Page 11: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/11.jpg)
Regular Reflection•All reflect waves are
parallel producing a good image
![Page 12: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/12.jpg)
Diffuse Reflection•Reflect waves from a rough surface bounce in
all directions producing a poor or no image
![Page 13: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/13.jpg)
Objects & Images•Objects & images are represented by arrows as to distinguish the top from the bottom

Virtual Image•Light rays focus on a
point behind the mirror
![Page 16: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/16.jpg)
Virtual Image•Virtual images are erect: image & object pointing in the same
direction
![Page 17: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/17.jpg)
Concave Mirrors•Light rays are reflect
from the inner (caved in) surface part of a hollow
sphere
![Page 18: Chapter 18 Mirrors & Lenses. Calculate the angle of total internal reflection in ignoramium (n = 4.0)](https://reader031.fdocuments.us/reader031/viewer/2022032105/56649cf95503460f949c9f8e/html5/thumbnails/18.jpg)

Spherical Aberration• The parallel rays reflected
off of the edges of a spherical concave mirror miss the focal point, blurring the image.

Lenses•Transparent material that allows that light to pass through, but refracts the light rays

thinner than the edges

the center is thicker than the edges

Concave Lenses•Parallel light rays
diverge when passing through a
concave lens

converge when passing through a
convex lens

Chromatic Aberration• The parallel rays passing
through a lens are refracted at the edges more so than at the center dispersing the colors

coating or double lens effect

Achromatic Lens• A lens that has been made
so that there is no chromatic aberration
