Which of the following forms of light can be observed with telescopes at sea level? Both visible light and radio waves pass almost freely through Earth’s atmosphere, and therefore are easily observed with ground-based telescopes.
Q. What are the two types of visible light telescopes?
There are two basic kinds of optical (gathering visible light) telescopes. Refracting telescopes use convex lenses, at the front of a tube, to gather and focus incoming light. The image formed is magnified for the viewer through an eyepeice lens at the back end of the tube.

Q. What can astronomers see in space using a telescope?
The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others.
Q. What type of telescopes are most effective when used in space?
X-ray telescopes, such as the Chandra X-ray Observatory, use X-ray optics to observe remote objects in the X-ray spectrum. The Hubble Space Telescope (HST), shown in (Figure below), is perhaps the best known space telescope.
Q. Which telescope is most powerful?
Giant Magellan Telescope
Q. What is the strongest telescope ever?
Webb
Q. What is the most famous telescope?
Hubble
Q. Which is the most massive object ever detected?
Published today in the journal Science, the research shows the system known as Cygnus X-1 contains the most massive stellar-mass black hole ever detected without the use of gravitational waves. Cygnus X-1 is one of the closest black holes to Earth.
Q. What is most dangerous animal in the world?
The 10 most dangerous animals in the world
- Cape buffalo.
- Cone snail.
- Golden poison dart frog.
- Box jellyfish.
- Pufferfish.
- Black mamba.
- Saltwater crocodile.
- Tsetse fly.
Q. What’s bigger than a blue whale?
While there might never be a larger animal than the blue whale, there are other kinds of organism that dwarf it. The largest of them all, dubbed the “humongous fungus”, is a honey mushroom (Armillaria ostoyae).
Q. Which types of radiation must you build a satellite to detect?
Astronomers have a huge problem detecting radiation from space because the Earth’s atmosphere blocks most of it and stops it from reaching the surface. Visible light and radio waves get through to telescopes on the ground, and some detectors (infrared, UV and gamma) work when they are high up on mountains.
Q. Which types of radiation can be observed from the tops of mountains?
Astronomers can observe some infrared wavelengths by putting telescopes on mountain tops.
Q. Is orange light a type of electromagnetic radiation?
Visible light is simply electromagnetic radiation in a range of wavelengths that our eyes are sensitive to. Visible wavelengths range from 0.0007 milimeters for red light, through orange, yellow, green, and blue, to 0.0004 milimeters for violet light. Ultraviolet is shorter wavelengths than violet.
