A water fountain is at the center of a circular pool as shown in Figure P1.59. A student walks around the pool and measures its circumference C. Next, he stands at the edge of the pool and uses a protractor to measure the angle of elevation of his sightline to the top of the water jet. How high is the fountain?
An underwater scuba diver sees the Sun at an apparent angle of 45.0 above the horizontal. What is the actual elevation angle of the Sun above the horizontal?
In Equation 4.4, the parameter looks like an angle but is not an angle that you can measure with a protractor in the physical world. Explain what represents.
Gg 1. Assume that pupillary distance between your two eyes is 63 mm. Write a calculator that determines the object distance based on the angle that an external point object distends between the pupils. Give the angle for objects at 30 cm, 1 m, and 10 m. Give your answers in degrees correct to 3 significant digits.
You have a concave spherical mirror (the same holds if you had a convex mirror) If the value of q (the distance from the image to the mirror along the principal axis of the mirror) is 0.68m and the distance of p (the distance from the object to the mirror along the principal axis of the mirror) is 3.37m, what is the focal length of the mirror? h B Al C h' The magnification equation and the sign convention for q imply that real images of real objects are always inverted (if both p and q are positive, m is negative); virtual images of real objects are always upright (if p is positive and q is negative, m is positive). Keeping the signs of p and q straight in your mind is the most challenging aspect of mirrors (and lenses). Fortunately, table 23.2 summarizes when p and q are positive and when they are negative.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A light beam reflects off two parallel reflecting surfaces that are { = 125 cm long and separated by a distance of s = 65.0 cm. If the beam of light enters this region as shown, with the angle 0 = 24.6°, determine the following. (a) the number of times the light beam reflects off the left surface 4.20 Have you redrawn the figure with all angles and distances labeled? How is the entrance angle 0 related to the angle of incidence and the angle of reflection for the mirrors? times (b) the number of times the light beam reflects off the right surface 4.20 How is the number of reflections off the right surface related to the number of reflections off the left surface? times Additional Materials
