The peak intensity of radiation from Star Beta is 350 nm. In what spectral band is this?

a)ultraviolet
b)radio waves
c)visible light
d)infrared radiation

help me understand please! <3

To determine the spectral band in which the peak intensity of radiation from Star Beta falls, we need to understand the electromagnetic spectrum.

The electromagnetic spectrum consists of a range of electromagnetic waves, ordered by their wavelengths or frequencies. It includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

In this case, the peak intensity of radiation from Star Beta is given at a wavelength of 350 nm (nanometers). To determine the spectral band, we need to compare this wavelength to the different regions of the electromagnetic spectrum.

Here is a breakdown of the different spectral bands:

- Radio waves: These have the longest wavelengths, usually greater than a few millimeters.
- Infrared radiation: This falls between microwaves and visible light, with wavelengths ranging from around 700 nm (red end of the spectrum) to 1 mm.
- Visible light: This is the region of the spectrum that is visible to the human eye and occupies a narrow range from approximately 400 to 700 nm.
- Ultraviolet radiation: This falls between visible light and X-rays, with wavelengths ranging from about 10 nm to 400 nm.

Based on the given wavelength of 350 nm, it falls within the range of ultraviolet radiation. Therefore, the answer is a) ultraviolet.

In summary, the provided wavelength of 350 nm for the peak intensity of radiation from Star Beta falls within the ultraviolet region of the electromagnetic spectrum.
