humans can typically see light in the range of 400 to 700 nm. however, some animals can see wavelengths outside of this range. for instance bees and some spiders can see ultraviolet light, while snakes and other reptiles have vision extending to the infrared wavelengths. what adaptive advantages might this extended vision offer these animals
Background:
Design and completely analyze an optical system to measure how fast the Sun is spinning,based on the Doppler shift between the west side of the sun (always turning toward us atvelocity v1) and the east side (turning away from us, also at velocity v1). It turns out the Sun hasvery sharp emission lines at a wavelength of λ = 630.0 nm. You may ignore Earth’s rotation andatmosphere.You’ll need at least 2 parts in your optical system. First, you’ll need to gather (maybe focus,maybe magnify?) the light from only the outer edge of the sun—no more than 5% of itsdiameter as seen from Earth. Be sure your system blocks out the rest of the sun when taking ameasurement of one side or the other. Second, you’ll need to very precisely and accuratelyseparate the sun’s spectrum into different wavelengths so you can measure the difference inwavelength caused by the Doppler shifts. You can use any combination of any optical elementswe have discussed in class: lenses, mirrors, pinholes,…
3) How bright will Pluto appear in reflected or scattered sun-light (total
Flux received in W/m²) at the Earth when Pluto is at Opposition and a
distance from the Sun of 40.0 A.U.? Assume that Pluto has an albedo of
0.60 and a radius of 1.2 x 10³ km.
