An optical telescope (as distinct from, say, a radio telescope). It's possible that the answer was intended to be "a refracting telescope" but reflecting telescopes use lenses as well.
Opaque and transparent materials differ between the amount of light that passes through it. Opaque materials do not allow any light to pass through. Transparent materials allow all or most light through.
Quartz can be transparent (clear) or translucent (you can see light through it, but shapes are very fuzzy).
Not exactly. A light telescope is a telescope that catches and shows visible light. The main light-gathering piece may either be a lens, in which case you would have a refracting telescope. Or - much more common with the larger telescopes - the main light-gathering piece is a parabolic mirror. In this case, it is a reflecting telescope. The largest refracting telescope is about 1.2 meters in diameter; all larger telescopes - currently up to about 8 meters - are parabolic mirrors.
Gathering and focusing light from distant objects.
Please refer to the link below. This will take you to a web site that discusses this. Multiwavelength astronomy is dedicated to observing the various spectrums of radiation emitted. That is called its light gathering ability. The 'aperture size' determines the amount of light (radiation) a telescope gathers This site might help you obtain a more in depth answer imagine.gsfc.nasa.gov IT IS CALLED "LIGHT GRASP" in an optical telescope and "RF GAIN" in a radio-telescope.
The biconvex transparent structure that focuses light on the retina is called the lens.
That's a "reflecting" telescope.
lens
The lens bends light that has entered the eye through the cornea and focuses it onto the retina at the back of the eye.
A magnifying lens. In a Refracting Telescope, a convex lens focuses light to form an image at the focal point.
Opaque - light does not pass through. Transparent - all light passes through. Translucent - some light passes through.
Transparent materials allow light to freely pass through them. Translucent materials also allow light to pass through them, but change the colour of the light.
An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrumcreate a magnified image for direct view, making a photograph, or collecting data through electronic image sensors.
Clear and transparent are the synonymous. A transparent material allows light to pass through. Opaque, on the other hand, do not allow light to pass through
An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.
an objects light can pass through is transparent
Yes, or lenses. Called reflector and refractors respectfully.
