Answer:
Green part of the visible spectrum.
X ray part of the electromagnetic spectrum.
Infrared part of the electromagnetic spectrum.
Explanation:
Wien's displacement law
Where, b = Wien's displacement constant = 2.898×10⁻³ mK
T = Temperature in kelvin
So, the wavelength would be of around the green part of the visible spectrum.
So, the wavelength would be of around the X ray part of the electromagnetic spectrum.
Human body temperature = 37°C = 37+273.15 = 310.15 K
So, the wavelength would be of around the Infrared part of the electromagnetic spectrum.
