[-/1 Points] DETAILS SERCP11 22.A.P.049. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Refraction causes objects submerged in water to appear less deep than they actually are. The fish in the figure below has an apparent depth of 1.37 m. Calculate its actual depth (in m). HINT Apparent Depth Actual Depth 2.49 ml m Need Help? Read It 8. [-/2 Points] DETAILS SERCP11 22.A.P.057. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A light ray enters a rectangular block of plastic at an angle 0, = 45.20 and emerges at an angle 0, = 77.7, as shown in the figure below. (a) Determine the index of refraction of the plastic. (b) If the light ray enters the plastic at a point _ = 50.0 cm from the bottom edge, how long does it take the light ray to travel through the plastic? ns 51.F Q Search ENG 12:00 AM Clear US 5/6/2023
