Explanation:
Given that,
The temperature of the surface = 90°F = 305.372 K
We need to find the wavelength of maximum energy emission of your body. According to the Wien's law,

Put all the values,

So, the required wavelength is equal to
.
Infiltration is the movement of water into the soil and run off is any snow or rain that wasn't absorbed fast enough and that would eventually drain into a watershed.
