Discussion Overview

The discussion revolves around the ability of prisms to separate different types of electromagnetic radiation, specifically focusing on radio and gamma rays. Participants explore the properties of prisms in relation to the electromagnetic spectrum, including the implications of using prisms for non-visible wavelengths.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions whether prisms can separate radio and gamma rays from sunlight, suggesting that both types of radiation might be present at the ends of the spectrum.
  • Another participant asserts that prisms primarily separate visible and near-infrared light, indicating that radio and gamma rays are not effectively separated by prisms.
  • A further contribution emphasizes that while electromagnetic waves of all frequencies are fundamentally similar, materials interact differently with various frequencies, leading to different behaviors in prisms.
  • This participant notes that gamma rays, due to their high energy, tend to pass through materials with minimal interaction, which can lead to significant atomic damage when they do interact.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of prisms in separating radio and gamma rays, with no consensus reached on the initial question posed.

Contextual Notes

There are limitations regarding the assumptions about the behavior of electromagnetic waves across different frequencies and the specific materials used in prisms. The discussion does not resolve the complexities of how different materials interact with various wavelengths.

I have a question about electromagnetic radiation, I drew this to better explain what I am trying to understand hopefully it makes some sense but what I was wondering is this... if you take two prism and let the light of the sun enter the prisms like in the picture I drew will they both have radio / gamma rays at the ends of there spectrums?

I think the answer is yes they do? If so could you "Stack" some of the light on top of each other?

The Sun emits radiation across a wide range of the spectrum and a small proportion of it includes radio and gamma rays (a very very small proportion of it is gamma rays. Almost zero). However a prism does not separate out anything but the visible and near-infrared range. Beyond that the radiation is either absorbed or passes through with little deviation.

Ok thank you.

We all get told that EM waves of all frequencies are basically the same. This is true but the materials they encounter are not the same. They do not behave the same way for all EM frequencies - which can be confusing. Glass and a few other substances happen to have (were selected for their uses because they have) similar behaviour with a limited range of EM frequencies. They do not absorb them (much) and the speed of light (related to refractive index) is different over the optical range. That allows us to make prisms etc for optical use. At other frequencies, those same substances will absorb the waves. Gamma rays are so high energy that they mostly pass almost straight through a substance, just occasionally making contact with a nucleus. When they do, they can serious damage to the atoms, even causing transmutation of an atom.
