If $\lambda _ { m \partial x } = 2.90 \times 10 ^ { 6 } / T$

Short Answer

If $\lambda _ { m \partial x } = 2.90 \times 10 ^ { 6 } / T$  expresses the relationship between Kelvin temperature and the wavelength of maximum intensity in nanometers, what is the wavelength in nanometers of maximum intensity for a star with a surface temperature of 7,250K?
