Please take you time if correct I will like:
Assume the mostly infrared radiation from a heat lamp acts like
a continuous wave with wavelength 1.50 µm.
(a)If the lamp's 205 W output is focused on a person's
shoulder, over a circular area 22.5 cm in diameter,
what is the intensity in W/m2?
_____ W/m2
(b)What is the peak electric field strength in kV/m?
_____ kV/m
(c)Find the peak magnetic field strength in µT.
_____ µT
(d)How long will it take in seconds to increase the temperature
of the 4.20 kg shoulder by 2.00°C, assuming no other heat
transfer and given its specific heat
is 3.47 ✕ 103 J/(kg · °C)?
_____ s
