The Broken Pencil-Ray Optics
A general classroom demonstration includes placing a pencil (or similar object) within an upright position within a round glass of water. The pencil is then slowly moved across the middle of the glass from a centered position to an off-center position. Since the pencil is moved across the middle of the glass, an interesting phenomenon is observed. The position of the pencil under the water is shifted associative to the position of the pencil above the water - the pencil appears broken.
Gamma Rays: The wave length of gamma rays is less than 10-11 m.
Longitudinal Wave A wave is a disturbance of a medium that transports energy by the medium without enduringly transporting matter. Within a wave, particles of the medium are te

Why diffraction can't occur if slit width is less than the wavelength of the light? Can you explain?
Determine where r is the position vector.
When are intermolecular forces the strongest? Intermolecular forces (dipole-dipole, dispersion and hydrogen bonds). These forces are weaker than chemical (covalent) bonds. Thus
