how does the angle of minimum deviation of glass prism vary if the incident violet light is replaced by red light???
what is the difference between polariser and analyser?
state the conditions for sustained interference of light.
Draw reflected wavefront when a plane wavefront is incident on concave mirror, convex mirror, concave lens and convex lens.
What is Fresnel distance? derive an expression for it.
explain the Huygens principle with example?
why are coherent sources required to produce the interference of light.
the intensity at the central maxima (o) in a young's double slit experiment is Io. If the distance OP equals 1/3rd of the fringe width of the pattern , show that the intensity at a point would be I0/4.in the experiment on diffraction due to single slit show that
I) The intensity of diffraction fringes decreases as the order n increasesii) angular width of the central maximum is twice that of the firdt order secondary maximum
what is the relation between polarising angle and critical angle
In a Young's double slit experiment the intensity at the cetral maxima is I0. Find the intensity at a distance
B(beta)/4 from the central maxima where B(beta) is the fringe width.
what is the difference between scattering and diffraction?
An experimental set up similar to young's double slit experiment to observe the interference of light.
Here SS2 - SS1 = lambda/4
write down the conditions for
(1)constructive interfernece
(2) destructive interference in terms of path difference S2p - S1P = delta
Does the central fringe observed in the above set up lie above or below O . Give reason
explian young's modulus by searle's method..
