PHYS 1122 College Playsics II Laboratory Basie Opties Post Laboratory Exercise use your calculator and your write-up and your notes and a ruler and protractor friends Caddo Loweny Date 11111 Below is shown a ray of light in air striking the side of a triangular prism, with an index o refraction 1.5. Reflect and refract the Tay at the first surface, but only refract it at the second surface. Extend both the reflected ray from the first flat surface and the transmitted ray thrown the 2 curved surface to show their point of exit from the page. There is no internal reflection going on here. Show any calculations you make somewhere on this page. In HD) 25.1

Answer 1

n=15 From Snell's law, n, Bin O = M2 Sin O2 at foint P = 1 (air) M2 & 15 (Glass) o = 40° Qar - sin 40° = 1.5 sing > = sun" (409) - 18= 25.374 1 at point o 1.5 sin (25-37) = sint =) t = sin! (1.5 sin (25.37) t = 40°]

Light from p bends at R as the medium changes. But the observed feels as it rays are Coming from Q. Hence an observer 0 sees the rish © At the depth less than it really is
