WAVE OPTICS : WAVE OPTICS A PRESENTATION BY KAJAL SENGUPTA
PART I : PART I BROAD OUTLINE OF THE CLASS (18/09/2009)
MAIN FEATURES
QUESTIONS ON COHERENCE AND INTENSITY OF TWO WAVES
PHASE AND ITS CALCULATION
NUMERICAL EXAMPLE FROM STANDARD TEXTBOOK
SOLVING QUESTIONS ASKED IN COMPETITIVE EXAMINATIONS BASED ON THIS TOPIC
FEW QUESTIONS : FEW QUESTIONS What is the usefulness of concept of Huygen’s secondary wavelets?
It helps us in finding the wavefront geometrically.
Two sources of light are coherent if they emit waves of -------- ----- with -------- ---------.
Same wavelength,constant phase difference.
Light waves propagate a distance of 10 cm( l1) in glass of R.I. 1.5 (n1) in time “t”. In the same time light wave propagates a distance 12 cm in a medium of R.I.( n2) what is the value of R.I of the medium? (solved on white board)
Two coherent monochromatic beams of light of intensities I and 9I are superimposed. What is the ratio of maximum and minimum possible intensities?( solved on the white board)
What , if the beams are non-coherent?
