Quiz for Homework 6 Started: Dec 12 at 5:33pm Quiz Instrucধons IMPORTANT NOTE: 1)You can only submit your answers once. But you don't need to complete the Quiz in one session, and as long as you... don't hit the "submit quiz" you can come back and update your answers! 2) For all questions you MUST enter all the values even if they are 0. If you leave an entry for a number blank, canvas grades them as being wrong. Question 1 1 pts Please refer to the spectral albedo curves shown below to answer the questions on the next page about a LandSAT-style multispectral sensor onboard an orbiting satellite. Assume a multispectral satellite sensor acquires data readings in 3 visible bands: “blue” = 400-500nm; “green” = 500-600nm; “red”=600-700nm; and 2 infrared bands: “nir” (near infrared)=700-800nm; and “thermal”=800-1200nm(i.e. 8 to 12 microns), so it measures intensity values in a total of 5 bands. Assuming a spectral irradiance with a uniform value of 1.0 across all wavelengths 400- 1200nm, and that the multispectral sensor has uniform spectral response of 1.0 within each band’s range of wavelengths, and 0.0 response outside that range, answer the following.12/12/2019 Quiz: Quiz for Homework 6 https://psu.instructure.com/courses/2020948/quizzes/3766027/take 2/13 C 1. a)the measured intensity value for water is highest in which visible band (answer choices are: red, green or blue)?
