The spectrum of a glowing filament has its peak at a wavelength of 1200 nm. What is the temperature of the filament, in °C?
The wavelength 10.0 mm is in the infrared region of the electromagnetic spectrum, whereas 600 nm is in the visible region and 100 nm is in the ultraviolet. What is the temperature of an ideal blackbody for which the peak wavelength lm is equal to each of these wavelengths?
You are working in a shop and are responsible for enacting the CoVID protocols before potential customers enter the shop (shoppers are not to be admitted if they have a temperature over 38.0°C). Unfortunately, the equipment you have been given to measure a person's temperature reports their peak wavelength instead. If a person has a peak wavelength of 9.320 μm, are they allowed to enter the store? A full solution must support your answer.
