Question

The peak intensity of radiation for a particular star occurs at a wavelength of 2.0 nanometers. In what spectral band is this?

Answer 1

X-ray.

Step-by-step explanation:

I had the same question on a test two weeks ago.

Answer 2

For a given peak intensity of radiation of a star that occurs at a wavelength of 2 nanometers, this is located at the spectral band of an X-ray. An X-ray's wavelength typically goes from 0.1 nano meters to 10 nano meters. Given that, the wavelength of the star fits perfectly into the range of an X-ray.
