The temperature of a pool of lava is measured at 1275 K.Given a Wien's constant value of 2898 μmK,what is the wavelength of maximum emission from the lava?
A)149838.63 μm
B)2)273 μm
C)0)213 μm
D)The answer cannot be determined from the information given.

According to Wien's Law, λ_max = (2898 μmK) / T, where T is the temperature in Kelvin. Plugging in the given temperature of 1275 K, we get: λ_max = (2898 μmK) / 1275 K = 2.273 μm. Therefore, the answer is B.

The Temperature of a Pool of Lava Is Measured at 1275
