11. For what angle of incidence the lateral shift produced by parallel sided glass siab is minimum |
| Answer» <p>for i = 90° lateral shift is maximum.</p><p>Lateral shift for a slab of t thickness = t x sin(i - r)/cosr</p><p>when i = 90</p><p>LS = t x sin(90 - r) / cos r = t x cos / cos r = t</p><p>L.S becomes equal to thickness t.hence for I=0° it is minimum</p> | |
