The intensity of electromagnetic waves from the sun is 1.4
kW/m2just above the earth's atmosphere. Eighty percent of this
reaches the surface at noon on a clear summer day.
Suppose you model your back as a 27 cm × 49 cm rectangle.
How many joules of solar energy fall on your back as you work on your tan for 2.0 h ?
Homework Answers
Solution)
Total Energy Fall = Intensity*Area*Time
= 0.8*1.4*10^3*27*49*10^-4*2*60*60
= 1066867.2 J (Ans)
=======
Good luck!:)

Electromagnetic Waves UV Radiation Some of us are all too familiar with the ill- effects of over-exposure to ultraviolet (UV) electromagnetic radiation, namely, sunburns (solar erythema). UV radiation can kill the skin cells immediately below the surface (part of the epidermal layer). Over the course of several minutes or several hours, as enough skin cells are killed or damaged, the body's natural immune response is triggered. The body responds to the damage with increased blood flow to the capillary bed of...
