Concept explainers
A submarine is 300 m horizontally from the shore of a fresh water lake and 100 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 210 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. (a) Draw a diagram of the situation, identifying the two triangles that are important in finding the solution. (b) Find the angle of incidence of the beam striking the water–air interface. (c) Find the angle of refraction. (d) What angle docs the refracted beam make with the horizontal? (e) Find the height of the target above sea level.

Then he descends to look at a coral reef so that his depth changes by 4/5 of the current value. Find Manuel's depth, relative to sea level, near the coral reef.arrow_forwardI need helparrow_forward
- A student is looking at the antenna on the roof of a building. The student is at a horizontal distance of 85.0 m from the building and the angle his eyes make is 38.0°, as shown. The student's eyes are 1.60 m above the ground. At what height is the antenna above the ground (from base of the building to the top of antenna)? 38.0° 85.0 m O 61.5 m O 39.7 m O 68.0 m O 55.6 m O 44.3 marrow_forwardA submarine is 285 m horizontally from the shore of a freshwater lake and 111 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 201 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. Draw a diagram of the situation, identifying the two triangles that are important in finding the solution.arrow_forwardOn a clear day a tiny fish hides under water (n water = 1.39 ) from an osprey under a circular leaf that has a diameter of 0.175 m. What is the maximum depth below the leaf that the fish can be so that it could not be spotted by the ospray? Provide your answer in meters with a precision of four places after the decimal.arrow_forward
- A fireman uses a 40 foot ladder to rescue a child from a window 30 feet above the ground. How far from the building was the base of the ladder set? (a) If x = 10 7ft. color the rest of the background black. (b) Ifx 50ft. color the rest of the background yellow.arrow_forwardI need help with part a and b of this question! Thanks! For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 51.0 km due east and have it detected by a light sensor that is 129 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. ANS:____º Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light. ANS:_____ marrow_forwardA submarine is 301 m horizontally out from the shore and 104 m beneath the surface of the water. A laser beam is sent from the sub so that it strikes the surface of the water at a point 242 m from the shore. If the beam just strikes the top of a building standing directly at the water's edge, find the height of the building.arrow_forward
- In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 56.0 km due north. A detector is placed 146 m due east of the laser. The mirror is to be aligned so that light from the laser refelects into the detector. (a) When properly aligned, what angle should the normal to the surface of the mirror make with due south? (b) Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is too large by 0.0050°. By how many meters (due east) will the reflected ray miss the detector?
