At the location of the Earth, the Sun's intensity is roughly
1000(W)/(m^(2))
. a) What is the strength of the electric field of the Sun's radiation at the Earth? b) The sunlight hits the mirrors on the Primm Valley solar collector array. The mirrors have an area of one square kilometer. What is the total force felt by the mirrors of the array? c) The sunlight also hits the waters of Lake Mead. Suppose you are swimming (underwater) in Lake Mead and see the sunlight coming toward you at 25 degrees relative to the normal. The index of refraction of the water is 1.33 . What is the angle that the sunlight hits the water's surface relative to the normal?
