What else can I help you with?
What purpose does ozone layer serve?
The purpose of ozone layer is to protect us from the harmful UV radiations from the sun. These are very harmful radiations and cause problems like skin cancer, eye cataract, modification in DNA etc.
Why do telescopes used for astronomy not have prisms to make the image the right way up?
Because it's not important. Introducing a prism into the optical path would absorb some of the light, which is important. So the tradeoff is an easy choice for astronomers to make.
Do x ray and gamma ray telescopes have the same design as an optical instrument?
No, x-rays and gamma rays cannot be focused by lenses or conventional telescope mirrors. To make mirrors that will focus x-rays or gamma rays you need very shallow glancing angle mirrors, that are nearly just parabolically tapered tubes. Typically several of these tubes with the same focal point but different diameter are nested inside each other.
What special name is given to spinning stars that transmit radio waves?
Pulsars are spinning stars that emit radio waves in narrow beams. These beams are like lighthouses in space, rotating at precise intervals and creating a pulsing effect as they are detected by radio telescopes on Earth.
Is ultraviolet radiation is visible or invisible?
It's detected by means of a camera that is sensitive to infra-red light. Visible light forms only a tiny portion of the electromagnetic spectrum.
Why do welders wear special goggles or facemasks with glass windows?
so that they can protect their eyes from harmful electromagnetic radiations.
What is the telescopes special uses?
To look at things in the sky\
Does and ordinary window glass have a very high transmissivity in the longwave infrared band?
No, ordinary window glass has a low transmissivity in the longwave infrared band. It absorbs and reflects the infrared radiation rather than allowing it to pass through. To improve transmissivity in this range, special coatings or materials can be used.
How do we see stars?
Either with our eyes, or with special instruments such as binoculars or telescopes.
What do ultraviolet telescopes see?
Ultraviolet telescopes are similar to optical reflecting telescopes, but their mirrors have special coatings that reflect ultraviolet light very well. Ultraviolet telescopes provide much information about interstellar gas, young stars, and the gaseous areas of active galaxies.
What design variants might one see in an optical telescope?
Some design variants you may see in an optical telescope include telescopes that fold or divert the optical path with mirrors and telescopes that use special lenses to enhance the images.
What radio astronomy?
That refers to researching the Universe by observing radio waves. Special telescopes - radiotelescopes - are built for this purpose; they are often quite large.
What Layers of the Sun can be seen with some type of telescope?
The photosphere, chromosphere, and corona of the Sun are typically visible with specific types of telescopes. The photosphere is the lowest layer and what we usually see with the naked eye, while the chromosphere and corona can be observed during a solar eclipse or with specialized solar telescopes that filter out the intense brightness of the photosphere.
Why is a x-ray machine a form of electromagnetic energy?
It is a form of electromagnetic energy because it uses special light rays to see through your skin/body to see your bones. It's heat and light is what makes it an excellent example of electromagnetic energy.
Where are all the special functions of the GoldenEye?
It can send out an electromagnetic pulse, causing a global computer meltdown.
What is the significance of the special spectrum in the field of physics?
The special spectrum, also known as the electromagnetic spectrum, is significant in physics because it represents the range of electromagnetic waves, including visible light, radio waves, and X-rays. This spectrum is crucial for understanding the behavior of light and other forms of electromagnetic radiation, and it plays a key role in various fields such as optics, telecommunications, and astronomy.
Why is the hubble telescope so special?
It is speacial because It can observe the heavans much better than ground telescopes. It is also the largest and most versatile space telescope
