Light
They are waves and also a particles at the same time.
What are light waves/photos?
It is the different range of frequencies and wavelength that light waves can have, including ranges as gamma rays, X-rays, UV, visible, IR, or radio.
What is the light spectrum?
These types of telescopes differ from refractors in the use of a mirror to focus the light.
What are reflector telescopes?
It is the last vissible layer of the Sun. Beyond it it is opaque.
What is the photosphere?
The oscillation of these fields produce light.
What are electromagnetic fields?
This range of wavelengths than can be detected with our eyes is not filter out by the Earth's atmosphere.
What is the visible spectrum?
This type of pollution is caused by close towns lamps
What is light pollution?
These surface photosphere features come from convection, last around 10 min, and can be as large as Texas.
What are granules?
It is the maximum speed that anything can get in the universe.
What is the speed of light?
This abstract body reflects no light and it emits light according to its temperature. With a maximum given by Wien's law.
What is a blackbody?
These molecules can absorb light, so it is better to put telescopes in high arid places.
What is water vapor?
This layer of the Sun extends for millions of miles and it is at millions of degrees kelvin.
What is the Sun's corona?
It is the speed of light divided by the frequency of the light waves.
What is wavelength?
This effect can give us the radial velocity of the star by looking at the red or blue shift of spectral lines.
What is Doppler effect?
These very expensive telescopes can avoid any atmospheric effects.
What are space telescopes?
These are places with strong magnetic fields that go perpendicular to the surface of the Sun.
What are sunspots?
This effect consists in the emission of electrons by an illuminated plate by some specific light waves.
What is the photoelectric effect?
These can be light or dark, and give us a pattern to identify different elements.
What are spectral lines?
This property determines the capacity of our telescope to collect photons. It must be larger for making sharper images.
What is telescope aperture?
These are produces when charged particles are expelled at big velocity after a coronal mass ejection.
What are solar winds?
The plasma particles that come from a prominence follow these lines producing an arc of plasma.
What are magnetic field lines.
