PHYSICAL SCIENCES DIRECTIONS: Most of the questions in the Physical Sciences test are organized into groups, with a descriptive passage preceding each group of ques- tions. Study the passage, then select the single best answer to each question in the group. Some of the questions are not based on a descriptive passage; you must also select the best answer to these questions. If you are unsure of the best answer, eliminate the choices that you know are incorrect, then select an answer from the choices that remain. Indicate your selection by blackening the corresponding circle on your answer sheet. A periodic table is provided below for your use with the questions.

Passage I (Questions 1–7) The Hubble Space Telescope (HST) is an astronomical satellite in low orbit above the earth’s atmosphere. The telescope provides the best photometric measurements ever to be achieved from any astronomical image. Light enters the telescope and is focused by the pri- mary mirror onto the secondary mirror. The secondary mirror then reflects light through a small hole in the pri- mary mirror to the focal plane, which is shared by redi- recting mirrors and electromagnetic measuring instruments. The redirecting mirrors send light to the guid- ance center and wide-field/planetary camera (Wiff-Pick). The rays of light that are not intercepted by the redirecting mirrors pass on to the instruments: the faint-object camera (FOC), the high-resolution spectrograph (HRS) and the faint-object spectrograph (FOS). Figure 1 The primary mirror is approximately spherical and has a focal length of 58 m and a diameter of 2.4 m. The sec- ondary mirror is flat and .3 m in diameter. The primary and secondary mirrors cooperatively focus the light at the focal plane. The mirrors are coated with aluminum and magne- sium fluoride, giving them the capability to reflect light with wavelengths between about 110 nm and 1 mm.
