Question 1 10 pts Components of some computers communicate with each other through optical bers having an index of refraction n =1.55. What time in nanoseconds is required for a signal to travel 0.33 m through such a ber? Your answer should be a number with two decimal places, do not include the unit. A person stands at the deep end of a swimming pool and looks at his dive mask which is at the bottom of the pool at a depth of 3.23 m. The index of refraction for water is 1.33. At what depth does the person see his dive mask (apparent depth in meters)? Your answer should be a number with three decimal places, do not include the unit. ? Actual depth Apparent depth Image Fish
