Problem 1. (a) Suppose the ratio between the frequencies of notes separated by half
a tone is f . There are twelve half-tones in an octave. Thus f 12 = 2 and f = 21/12 = 1.0595.
(b) 1 : f 4 : f 7 = 1 : 1.26 : 1.50

Problem 1 (mirage). Suppose at height h0 the light is coming in at angle 0 to the
normal. Thereafter, for any two adjacent slabs we have Snells law: ni sin i = ni+1 sin i+1 .
Therefore, as the light prop
