When the sun is either rising or setting and appears to be just on the horizon, it is in fact below the horizon. The explanation for this seeming paradox is that light from the sun bends slightly when entering the earth’s atmosphere, as shown in Fig. Since our perception is based on the idea that light travels in straight lines, we perceive the light to be coming from an apparent position that is an angle d above the sun’s true position. (a) Make the simplifying assumptions that the atmosphere has uniform density, and hence uniform index of refraction n, and extends to a height h above the earth’s surface, at which point it abruptly stops. Show that the angle d is given by as attached. where R = 6378 km is the radius of the earth. (b) Calculate d using n = 1.0003 and h = 20 km. How does this compare to the angular radius of the sun, which is about one quarter of a degree? (In actuality a light ray from the sun bends gradually, not abruptly, since the density and refractive index of the…
Humans are unable to convert radiant energy from the sun into stored energy that can be usedto do work. Plants, however, obtain their energy from photosynthesis – sunlight is used toconvert carbon dioxide and water into sugars (stored as an energy source) and oxygen.Consider a leaf with a surface area of 2.5 cm2. On a sunny day it might receive sunlight withan average power per unit area of 350 W/m2. Of this incident light, only about 40% is usefulfor photosynthesis. (a) If the process was perfectly efficient (i.e. all the useful radiation was converted tostored internal energy), calculate the increase in internal energy of the leaf in aperiod of one hour. (b) In practice, the overall efficiency of the process (percentage of energy storedrelative to the total incident energy reaching the surface of the leaf) is only about6%. Discuss, in relation to the First Law of Thermodynamics, what happens to theremaining energy?
