One way of realizing reflectors, used for example in guide posts, consists of using many small transparent spheres, each of which has one hemispherical surface silvered. Determine how large the refractive index of the sphere material must be so that a large part of the light entering the sphere from a distant source is reflected back in the direction of incidence. In doing so, you may restrict yourself to considering rays that pass close to the centre of the sphere. Problem 4 (11 points) Soap bubbles The pressure exerted on its interior by the thin skin of a spherical soap bubble is approximately inversely proportional to the radius of the soap bubble. a) Show that the proportionality factor is given by four times the surface tension between the soap skin and the air. If two soap bubbles with radii R1 and R2 are carefully connected with a thin drinking straw, the air flows from one of the bubbles into the other and a single bubble of radius R3 forms. b) Consider the case R1 < R2 and state which of the soap bubbles contracts. Determine the radius R3 of the resulting soap bubble when the air pressure is much greater than the pressure produced by a soap bubble skin. In an experiment, at an air pressure of 1,0 105 N m-2 the following values for the radii of the soap bubbles were determined, each with an error of 0.1 cm.
