ISP 205: Visions of the Universe Fall 2009, Section 1 The following is a study guide for the Frst test. IMPORTANT CAUTIONARY NOTE: This is a general outline of the material that will be covered on the exam. It may be useful in helping you to spend your time studying the most relevant material. However, it is only an outline, and is NOT a replacement for studying your notes, the appropriate sections of the book, and the homework. - An idea of the scale of the Solar System and the universe. The constancy of the speed of light, and its implications. - Why the Sun and stars rise and set as they do. Why the Moon appears in the sky as it does. The origin of the seasons. The overall motions of the Earth, Moon, Planets, and Sun. The evidence that led to the understanding of the motions of the Earth and planets around the Sun. - How and why objects move. Newton’s Laws (and that these explain Kepler’s laws), Gravity - what it is, how it works. Note: just because the description of this part is short, does not mean

Unformatted text preview: it is not important.- Radiation (light). Electromagnetic radiation = light. Light is a photon - has wave and particle properties. Each photon has a wavelength, and a speciFc energy. Understand what a wavelength is, how it relates to frequency, and how the energy is related to the wavelength. The change of the brightness of objects with the change of distance between the observer and object. The properties of glowing bodies at di±erent temperatures. A general idea why atoms emit/absorb at speciFc wavelengths, and how these are useful for astronomy. What the Doppler shift is.- What makes telescopes useful for astronomy. Why telescopes are located where they are. Advantages of telescopes in space.- The inventory of the solar system - what is in it and where it is. How the planets orbit around the Sun. The basic di±erences between the terrestial and giant planets. Usual reminder the material on the test was all covered in lecture. Look at the homework and old question....
