Compared to optical telescopes, radio telescopes are built large because?

Radio telescopes are often used in astronomy because they have a much larger range than optical telescopes. This is due to the fact that radio waves can travel through denser materials, like clouds and dust, with less obstruction. They also have better resolution than optical ones, allowing for more detail to be seen in an image.

The biggest difference between these two types of telescope is the size. Radio telescopes need to be built large and tall so that they can capture as much radiation from space as possible. Optical ones do not need such a big device because light travels in straight lines which makes it easier to focus on smaller objects or targets from farther away.

The only real downside to radio telescopes is the fact that they need a lot of land space which makes them hard to build because they are so large. There’s also no way for astronomers to see what they’re looking at while it happens, and this makes visual confirmation impossible.

Optical ones have a more limited range than these but there’s hardly any obstruction in their path. The upside here is that if we can’t see something as exactly with an optical telescope then we can always use another one on top of it or next to it until we get enough data points from all different angles.” Radio Telescopes: Better Resolution + Can Penetrate Denser Materials = Greater Range – Difficulty Finding Land Space + Unable To Visualize What
