Black hole - frequencies used for viewing

In summary, different frequencies are chosen for viewing stars in space missions because they are emitted by different types of objects and can penetrate different things in space. The specific frequencies used to view a black hole may be due to other parts of the spectrum being blocked or the black hole emitting radiation at those frequencies.

Hey,

In space missions why do they choose different frequencies for viewing stars?

For example why do they choose both 43 GHz and 230 GHz to view a black hole?


Cheers!

Different frequencies are emitted by different types of objects. They also can penetrate different things in space, such as visible light being blocked by dust while radio-infrared is able to penetrate it. I can't say why 43 ghz and 230 ghz is used to view certain black holes, but I assume it's either because much of rest of the spectrum is blocked or because the black hole emits radiation specifically at these frequencies.
 

1. What frequencies are used to view black holes?

The frequencies used to view black holes vary depending on the type of observation being conducted. For optical observations, visible light frequencies are used. For radio observations, low-frequency radio waves are used. For X-ray observations, high-energy X-rays are used. Infrared and gamma-ray frequencies can also be used for certain observations.

2. How do these frequencies help us see black holes?

These frequencies help us see black holes by capturing different aspects of their behavior. For example, visible light frequencies can show us the accretion disk around a black hole, while X-ray and gamma-ray frequencies can reveal high-energy jets being emitted from the black hole.

3. Why are multiple frequencies needed to view black holes?

Multiple frequencies are needed to view black holes because each frequency captures different aspects of their behavior. By using multiple frequencies, scientists can gather a more complete understanding of the black hole's properties and behavior.

4. How are these frequencies detected?

These frequencies are detected using specialized instruments such as telescopes, detectors, and satellites. These instruments are designed to detect and measure specific frequencies of electromagnetic radiation, allowing scientists to study black holes at different wavelengths.

5. Can we view black holes using visible light?

Yes, it is possible to view black holes using visible light frequencies. However, visible light observations may not always be the most effective for studying black holes due to their low luminosity and the presence of dust and gas that can obscure our view. Other frequencies, such as X-rays and radio waves, may provide a clearer picture of black hole behavior.
