You and your friend Bruce are experimenting with a red lamp shade and blue lamp shade. You place lamp shades individually over a 120-W light bulb. Assume that the light radiates from the lamps uniformly and 9.5% of their power is converted to light. (a) What is the average intensity of the light at 1.6 m from the red (A = 710 nm) lamp shade? W/m2 (b) Is the average intensity of the blue (A = 480 nm) lamp shade at 1.8 m greater than, less than, or equal to the intensity calculated in part (a)? greater than O less than

A community plans to build a facility to convert solar radiation to electrical power. The community requires 2.60 MW of power, and the system to be installed has an efficiency of 30.0% (that is, 30.0% of the solar energy incident on the surface is converted to useful energy that can power the community). Assuming sunlight has a constant intensity of 1 200 W/m2, what must be the effective area of a perfectly absorbing surface used in such an installation?
Excerpt from (Tsai & Hamblin, 2017) “Infrared (IR) is a type of electromagnetic radiation, including wavelengths between the 780 nm to 1000 μm. IR is divided into different bands: Near-Infrared (NIR, 0.78~3.0 μm), Mid-Infrared (MIR, 3.0~50.0 μm) and Far-Infrared (FIR, 50.0~1000.0 μm) as defined in standard ISO 20473:2007 Optics and photonics -- Spectral bands (Vatansever F, 2012). Several studies have reported that IR can improve the healing of skin wounds, photoprevention, relieve pain, stiffness, fatigue of rheumatoid arthritis, ankylosing spondylitis, potentiate photodynamic therapy, treat ophthalmic, neurological, and psychiatric disorders, and stimulate the proliferation of mesenchymal and cardiac stem cells (Vatansever F, 2012), (Tsai SR, 2015) (Barolet D, 2015).Soccer players have used FIR emitting clothing (density of 225 gm−2, 88% far IR radiation emitting polyamide 66 Emana yarn (PA66) fiber, 12% Spandex, emissivity of 0.88 and power emitted of 341 W/m2 at 37°C at 5–20 μm…
