Diffraction Ap

When lightof a single wavelength ,

from laser , strikes a diffraction

grating it is diffracted to each side in

multipleorders. orders 1 and 2 are

shown to each side of the direct beam.

Diffraction in atmosphere

When light travels throughthin clouds madeup of

nearly uniform sized water droplets,diffraction of

lightat the edgesof the particles.This degree of

bending of lightdependson the frequency (color)

of light. The result is a patternof rings, which seem

to emanatefrom the sun, moon,planetor other

astronomical object.

The apparatus consists of electric

vibrator, a friction less pulley, a

light weight pan, a meter rod, a balance,

a weight box, a string of uniform

Tattoo machine

A tattoo machine is a hand-held device is used

to create a tattoo, on the skin with indelible

ink. Modern tattoo machines use alternating

electromagnetic coils that can control needle

depth, speed, and force of application, which

has allowed tattooing to become a very precise

art and helps to move a needle bar up

and down, driving pigment into the skin

Making up of a hologram

Basics of Hologram

To record a hologram, some of the light scattered from an object or a set

of objects falls on the recording medium. A second light beam, known as

the reference beam, also illuminates the recording medium, so that

interference occurs between the two beams.

Security

The presence of holograms

indicates the authenticity of

these items. The security

holograms are used in
