How far apart must two objects be on the moon to be distinguishable by eye if only the diffraction effects of the eye’s pupil limit the resolution? Assume 550 nm for the wavelength of light, the pupil diameter 5.0 mm, and 400,000 km for the distance to the moon.
Descriptive Astronomy Week of February 5-11 *Side note: I know we had an exam this week so the notes only consist of what was went over on Tuesday. Chapter 6: The Terrestrial Planets Mercury (The Lunar Doppelganger) o Closest planet to the sun. o Takes about 88 days to revolve around the sun. o Scarps- look like wrinkles on the surface. o Surface temperature can reach over 400 degrees. o Is at perpetual twilight. Permanent shadow at the poles. o Has almost no axial tilt. Tilt is 2.11 degrees. o Solar wind can kick neutrons off the planet surface and if there is water present the number of neutrons kicked off will decrease. Because of this prediction, it has been proven that Mercury has ice water at its north and south poles. Venus (Planet of “Tough” Love) o Atmosphere is thick because of CO 2 Pressure is 90 times that of Earth’s. o High in the atmosphere is sulfuric acid rain. Rain doesn’t touch the surface. o Has lightening that may be caused by volcanic activity. o No large bodies of water. o Has extensive lava flows, volcanic structures, and “Pancake Domes”. o Pancake Dome- also known as a “Lava Dome” is an unusual type of volcano found on Venus. Domes could spread for miles. o Only a few
