Question

Name: Daily Problem(s) #31 The U.S. (really mankind- ALL of us), first walked on the moon on July 16, 1969 (50 years ago). The moon reflects many wavelengths, one is 601.1 nm. May find the following constants useful h = 6.626x10Js and speed of ALL EM radiation.c2.9981109 m/s) a. About 50% of the moon is made of Si02. Give the best IUPAC name for SiO2. Worke / charges..... b. What color/part of the EM spectrum does the moon reflect the 601.1 nm)? See spectrum below Increasing Frequency (v) 1919 1910 1910 10 10 10 10 10 10 L X rays IR UN Microwave M ave yray AM L 10 - 10 10 10 m) 10 10 10 10 10 Increasing Wavelength (..) - Ver Purple blue green yellow orange red SOO Increasing Wavelength() in am Edited from Wikipedia c. Calculate the energy (in J) of the 601.1 nm EM radiation. Show math! d. If light travels 384,400 km (from earth to moon). How long does that take? In other words, what was the delay between the moon lander and mission control when they talked to and from the moon in seconds)? (Hint: Try unit analysis)
