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.
Draw a picture of a moving source and the waves surrounding it according to what you observed in this experiment. How does the spacing of the wavefronts in front of the source comp
A capacitor and a coil are linked in series. The capacitor is charged and allowed to discharge by the coil. The current that will then flow by the capacitor-coil combination
An engineer is using DSC to determine the fiber volume fraction of a carbon fiber / epoxy prepreg. It is known that the heat of reaction of the pure, fresh epoxy resin (no carbon
Voltage division: In a series circuit Ohm's law applies for each component. However, since the current is common to all components we have: V1 = IR1, V2 = IR2,
Q. Explain Snells Law? It is believed that Snell developed his well-known equation by purely empirical means. He made various measurements of the refracting properties of vario
The energy needed to ionize an atom is known as ionization energy. It is the energy needed to make the electron jump from the present orbit to the infinite orbit.
