Question1
Calculate the intensity distribution in a standing evanescent wave above a glass/air interface created by counter-propagating evanescent of the same intensity and polarization. Take a line profile perpendicular to the interference fringes and calculate the convolution with a Gaussian of a given line-width. How does half-width influence the fringe visibility?
Question2
A 78 g bullet travelling at 300m/s penetrates a block of ice at 0 Celsius and comes to rest within the ice .assume that temperature of the bullet doesn't change appreciably, how much ice is melted as an outcome of the collision?
Question3
The sand is removed and a 1.0--mass block is placed on each cap. After caps have moved (if necessary) to re-establish equilibrium, is the right cap higher, lower, or the similar height as the left cap?
