Question

Suppose the temperature of a COVID positive patient is recorded as Tbody = 40°C.

Determine the wavelength at which the radiation emitted from the body reaches its peak.

Answer 1

Solution

Temperature

T=40°C=313K

Using wein law

$\lambda=\frac{b}{T}\\=\frac{ 2.898 \times 10^{ -3 } }{313}\\=92.59A°$
