It remains constant with changing wavelength at a given temperature.

The emissivity and absorptivity of a gray body are independent of wavelength.

It remains constant.
Mohit said:

Yes, it remains constant.

It remains constant. Because monochromatic radiative properties for grey body doesn't depends on wavelengths.
