Stars emit all kinds of radiation including light waves, cosmic rays, gamma rays, and X-rays. When we look at stars, we can only see the light waves.
But using cameras that can 'see' the other wavelengths, particularly X-rays, then convert them to light waves that we CAN see, we notice a lot of things that simply do not show up by looking at the stars' light waves.
What else can I help you with?
How are electromagnetic waves used to operate an xray machine?
Electrons impact at high velocity on a tungsten anode. The tungsten emits the X-Rays, which are the electromagnetic waves.
Which form of energy are optical telescopes used to study?
Optical telescopes are used to study electromagnetic energy in the form of visible light. This allows astronomers to observe and study objects in the universe, such as stars, planets, galaxies, and other celestial bodies that emit or reflect visible light.
What are the instrument that is used to study stars?
telescopes
Why would physics be used to study the movement of ocean waves?
Ocean waves are made of matter
A graph used to study the stars?
An HR gram
What types of waves are found in electromagnetic spectrum for studying the universe?
The waves are called "electromagnetic waves". All types of EM waves can be used to study the Universe.
What are other instruments used by the astronomers to study about stars?
Telescopes
Why is the electromagnetic spectrum such as radio waves used to study space?
Most stars and many other objects in space emit radio and microwave radiation. Even the big bag emitted electromagnetic radiation.
What is the scientific instrument used to study the the light that comes from stars?
Spectroscope
What are two areas of compressional waves?
Two areas of compressional waves are seismology, where they are used to study the Earth's interior and detect earthquakes, and medical imaging, in which ultrasound waves are used for diagnostic purposes.
What is energy traveling as EM waves used to gather images of outer space called?
The energy is called electromagnetic energy. It is the energy carried by electromagnetic waves. In principle, any frequency of EM waves can be used to gather information about objects in outer space.
Why is ultrasonic not used in radar?
ultrasonic waves are not used but radio waves are used in radar technology because ultra sonic waves generally create an image out of the object while we have to confine our study to the geometrical measurements only
