Smurf in solarium · Estonian PhO 2011 #4

Physics

Problem

Smurf spent

t = \SI{10}{min}

under the lights of a solarium. What heat

Q

did Smurf receive? The incident light spectrum

I

of Smurf (intensity per wavelength depending on the wavelength of the light, unit \SI{10e9}{W/m^3}) and the absorbed spectrum

\varepsilon

of Smurf (the relation between the absorbed and incident intensity as a function of wavelength) are given in the figure. The effective area where the light falls on Smurf is

S = \SI{0,1}{m^2}
