Questions Related to interference
To demonstrate the phenomenon of interference, we require two sources which emit radiation of.
A light of wavelength $400\overset{o}{A}$ after travelling a distance of $2\mu m$ produces a phase change of:
To demonstrate the phenomenon of interference of sound, we need:
Two coherent sources of intensity ratio $\beta$ interfere. Then the value of $\displaystyle \left( {\frac{{{I _{\max }} - {I _{\min }}}}{{{I _{\max }} + {I _{\min }}}}} \right)$ is:
Coherent sources for studies in interference of light are obtained from.
Interference fringes were produced in Young's double slit experiment using light of wavelength $5000\overset{o}{A}$. When a film of thickness $2.5\times 10^{-3}$cm was placed in front of one of the slits, the fringe pattern shifted by a distance equal to $20$ fringe-widths. The refractive index of the material of the film is?
True & False Statement Type
$S _1$ : In an elastic collision initial and final K.E. of system will be same.
$S _2$ : In a pure L-C Circuit average energy stored in capacitor is zero.
$S _3$ : In YDSE coherent sources are formed by division of wave front method.
$S _4$ : If a physical Quantity is quantized then it must be integral multiple of its lowest value.
