PIEZOELECTRIC EFFECT -- PRODUCTION OF ULTASONIC WAVES

When an AC Voltage is applied across a piezoelectric crystal such as Quartz Crystal, It vibrates at the frequency of the applied voltage. Vibration of maximum amplitude occurs at the natural resonant frequency of the crystal which is determined by physical dimension and by the way the crystal is cut. The Frequency is given by .......

Projectile Motion, Introduction to Projectile Motion

MOTION OF A PROJECTILE

When a particle is thrown into space in any position at an angle with respect to horizontal or vertical direction. Its subsequent motion is subjected to only gravitational forces.

A Projectile travels both in horizontal and vertical directions and traces curvilinear path which is parabolic. The necessary conditions for a body to be called a projectile are:

1) It should be given some initial velocity.
2) It should move under the action of gravity alone, there should not be any other driving force.

IMPORTANT TERMS:

Angle of Projection:  Angle at which particle is thrown with respect to horizontal.
Horizontal Range: The horizontal distance covered by particle during its motion.
Time of Flight: The time interval of particle when it remains in motion.
Height of Projectile: The maximum height reached by projectile from reference line is called Height of Projectile.

ROTATIONAL MOTION -- CIRCULAR MOTION

In Rotational (Circular) Motion, The movement of particle is along a circular path. The particle repeats its journey along the same circular path about same centre of rotation which remains fixed.

GENERAL PLANE MOTION

There exists certain situation where a body is having both motions of translation and rotation simultaneously at a particular instant. Examples of such a combined motions are:
• Motion of roller without slipping.
• Motion of a wheel of locomotive train, truck, car etc.
• A rod sliding against a wall at one end and floor at other end.

Relative Velocity, Relative Velocity Concept

RELATIVE VELOCITY

Consider two trains A and B moving in parallel tracks and in the same direction with velocities 60 km/hr and 45 km/hr respectively. These are absolute velocities with respect to a fixed frame of reference. To a passenger sitting in train B, the train A will appear to be moving with a speed of (60-45) = 15 km/hr.

DIFFRACTION OF X-RAY - LAUE SPOT - LAUE METHOD

The wavelength of X-Ray is in the order of 1 Angstrom ordinary grating which have 6000 line per inch cm cannot produce diffraction pattern of X-Ray. There in the case of X-Ray instead of ordinary grating, Crystal Grating are used. Hence a crystal grating is a three dimensional space grating when a narrow beam of X-Ray is allowed to pass through a crystal. The X-Rays are diffracted in different direction and form a symmetrical pattern of spot on a Photographic plate.

LAUE EXPERIMENT
When X-Ray passing through crystal of ZNS or NaCl, the transmitted beam form a diffraction pattern on the photographic plate. IF this photographic plate is ...........
