Question A: part 1,2,3

When viewed from the ground, the sun is 57° above the horizontal (0 in the figure). At what angle above the horizontal does the sun appear to be to a fish in the water? The index of refraction of the air is 10 and of the water is 1.3. stion air, n = 1.0 water, n = 1.3 FI Select one: TI 65.2 53.6 La 44.9 773 73.0

Answer 1

current in Rc circuit - Rd 1 + = Ime an 0 = 57 R at time to 2 waterna 0 = 90-57 I (+= 0) = x = 10 - 12 (1) Here, o so = 33 from snell's low n, sino = n₂ sin oz (1) sin 33 = (1.3) sino 3 sind = (/1.3) sin33 a sino 0.419 > O = sin(0.418) = 24,7 the sun will appear to the fish at du angle 0+0₂ = 57 +24.7 81. 7 above the horizontal of the measured light spect nem is shifted towards lover frequencies, then according to Doppler Effect of light = Dolc-u receding frequency The galaxy's is relative motion away from the Earth
