If a hologram is made using 600-nm light and then viewed with 500-nm light, how will the images look compare to those observed when viewed with 600-nm light? Explain.
A two-slit interference experiment is set up, and the fringes are displayed on a screen. Then the whole apparatus is immersed in the nearest swimming pool. How does the fringe pattern change?
How could you very quickly make an approximate measurement of the focal length of a converging lens? Could the samemethod be applied if you wished to use a diverging lens? Explain.
Explain, using phasor diagrams, why each statement is true. (a) A minimum occurs whenever ϕ is an integral multiple of 2π/N, except when ϕ is an integral multiple of 2π (which gives a principal maximum). (b) There are (N-1) minima between each pair of principal maxima.
Ordinary photographic film reverses black and white, in the sense that the most brightly illuminated areas become blackest upon development (hence the term negative). Suppose a hologram negative is viewed directly, without making a positive transparency. How will the resulting images differ from those obtained with the positive? Explain.
