See, when white light enters the prism it has actually entered out atmosphere and so the parts of EM spectrum like UV don't appear. After the light comes out of the prism all the parts seprate but we can only see the visible part i.e. 400-700nm range. So we look at only a part of the EM spectrum. Hence option B is correct.

Explanation:

When white light is split into its component colors by a prism, we see different colors ranging from red to violet. This phenomenon is called dispersion of light.

Electromagnetic Spectrum:

The electromagnetic spectrum is a range of different types of electromagnetic radiation, which includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Looking at a part of the electromagnetic spectrum:

When white light is split into its component colors by a prism, we are not looking at the entire electromagnetic spectrum. Instead, we are only seeing a small portion of the spectrum, which is the visible light region. Visible light is the portion of the electromagnetic spectrum that is visible to the human eye and ranges from approximately 400 to 700 nanometers in wavelength.

Conclusion:

Hence, option B is the correct answer as we are looking at a part of the electromagnetic spectrum, which is the visible light region when white light is split into its component colors by a prism.

This type of study is called astronomical spectroscopy.The science of spectroscopy is quite sophisticated. From spectrum lines analysis astrophysicists can determine not only the element, but the temperature and density of that element in the star. The spectral line also can tell us about any magnetic field of the star.The width of the line can tell us how fast the material is moving. We can learn about winds in stars from this. The shifting of spectral lines shift back and forth indicates that the star may be orbiting another star.The following table shows a rough guide for the relationship between the temperature of a star and the electromagnetic spectrum.If the spectrum of a star is red or blue shifted, then it can be used to infer its velocity along the line of sight. Edwin Hubble observed that more distant galaxies tended to have more red shifted spectra. This establishes the theory of expansion of the universe.Q. What is astronomical spectroscopy?
