Solution)
Given,
Intensity, I=1.4 kW/m^2
Area, A=33 *55 cm
We know,
Energy= Intensity*time*Area
So, Energy=(0.8*1.4*10^3)*(0.33*0.55)*(0.5*3600)
Energy= 365904 J (Ans)

Electromagnetic waves from the sun with an average intensity of 1400 W/m^2 illuminate the upper atmosphere. What is the peak strength of the magnetic field associated with these waves? 2.9 Times 10^5 T 3.4 Times 10^6 T 2.4 Times 10^-6 T 4.1 Times 10^5 T 5.9 Times 10^-2 T
Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of 1.38 kW/m2. (a) Assuming that Earth (and its atmosphere) behaves like a flat disk perpendicular to the Sun's rays and that all the incident energy is absorbed, calculate the force on Earth due to radiation pressure. (b) For comparison, calculate the force due to the Sun's gravitational attraction. Assume that the speed of light and Earth radius are 2.998 × 108 m/s and 6.37 thousand km...
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...
