Q1 Thin Film Engine oil (n = 1.50) has spilled onto a smooth flat lake (n = 1.33), spreading into a thin surface film of thickness, d. Sunlight illuminates the lake, reflecting from an incident angle of 45° to your eye. Your eye detects sunlight in the 400 to 740 nm wavelength range. (a) [3 mark] State an equation for wavelength, 2m, that satisfies the bright intensity fringe condition at the 45° viewing angle. (b) [2 marks] Determine the minimum...

.(3 pts) Suppose you shine an orange sodium laser (A =600 nm a in vacuum) nearly perpendicularly into a pool of water (nh20= 1.30) that is covered with a thin film of oil (noi=1.25). You notice that the oil film acts like an anti-reflective coating at the wavelength of your laser, meaning that the reflections are completely destructively interfering Given this observation, what can you conclude as the minimum thickness of the oil film? (Hint: Start by carefully drawing out...

4. An exothermic material is encased in a 1-m-long thin tubular sleeve. The material generates heat at a steady rate of 4800 W/m. The thermal conductivity of the exothermic material is 22 W/mK. The radius of the tube is 30 cm, and you can neglect the thickness of the sleeve. Also assume the ends of the tube are perfectly insulated. (a) If the tube is exposed to air at 20°C, and if the convection coefficient between air and the tube...
