I will write information on a few optical devices. please add your description.
For each device, please show a diagram, its working principle, formulas for the device, how the device is used in real life.
A. Spherical mirrors
1. concave mirror
used as reflectors of light by a dentist - doctor.
in some physics experiments, to measure deflection.
car/vehicle head lights
2. parabolic reflector mirror
It is used in reflective telescopes;
3. convex mirror
used in rear view mirrors on vehicles, in super markets, junctions, etc,
in some instruments, to be able to see behind of some parts inside the devices.
4. plane mirrors
make-up table , bath rooms
5. in place of walls on buildings, for cooling
1. Double convex lenses
2. Double concave lenses
3. Plano-convex lenses
4. plano concave lenses
5. concave-convex lens
6. spherical lenses
used in spectacles worn to correct defects in the eyes
convex lenses are
used in telescopes, microscopes.
there are astronomical telescopes
terrestrial telescopes - to watch sports matches,
still cameras , video cameras,
Lenses are used in movie projectors, over head slide projectors
prismatic cameras use prisms
convex lenses are used in normal cameras
used to determine refractive index
study dispersion of light
F. computer data storage devices - CD ROM .. optical storage devices
G. Laser devices
H. optical fibre devices - decorative pieces, telecommunication devices
I. optical light sensors - optical detectors, optical transducers
used in fibre optic telecommunication
J. lamp shades, tube lights - to distribute light in a uniform way in the room
