A goldfish is swimming inside a spherical bowl of water having an index of refraction n = 1.333. Suppose the goldfish is p 10.4 cm from the wall of a bowl of radius |R| = 15.8 cm, as in the figure below. Neglecting the refraction of light caused by the wall of the bowl, determine the apparent distance of the goldfish from the wall according to an observer outside the bowl. 1.07 Your response differs from the correct answer by more than 10%.

The Rayleigh criterion provides a convenient way to describe the theoretical resolution (e.g. an ability to distinguish objects ) of an optical system. The criterion states that two small bright sources of light can be resolved if the first d mìnimum of the image of one source point just coincides with of further apart then the first maximum of another (s Ho Your c below). A converging lens, 28.7 mm in diameter, is used to form images of distant objects. Considering the diffractio lens, what angular separation must two distant point objects have in order to satisfy Rayleigh's criterion? Assume t Here wavelength of the light from the distant objects is 469 nm. Provide your answer in millidegrees (mdeg). STE Exp complexity subscibers Answer: Choose... + Check Finishin Check c

A beam of light is incident on a square piece of glass with side s = 10.0 cm and index of refraction 1.50. The angles are shown in the figure to scale (you can count the blocks to measure them if you don't have a protractor). Where does the beam exit the glass? Assume the glass is in air (n = 1.00).
