Why should photons emitted by a hotter gas have, on average, shorter wavelengths than photons emitted by a cooler gas?

According to wein's law,

wavelength has inverse relation with temperature

so that's why hotter gas has shorter wavelength than cooler gas.

hope this answer is correct

i think if it were me i whould divide 300 dide 15
