Why was reflecting telescope invented?
Early lens telescopes were small, expensive, made from delicate glass, and had fringes of violet color around bright objects. People could make mirrors, first of polished metal, then from glass coated with silver, and finally from different glasses coated with aluminum and other chemicals. These mirrors are larger, cheaper, and reflected light without making the color fringes. The reflecting telescope made modern Astronomy possible.
What does a telescope reflect?
A reflecting telescope is an optical telescope which uses mirrors to bring the light to a focus. The first one was designed by Isaac newton.
What was the name of the metal that covered the toenails and fingernails of the dead Egyptian pharaohs?
the unforgeterble orgasim
How do the parts of a reflecting telescope work together to view faraway objects?
There are a variety of styles of reflecting telescopes, but I will describe one of the easier and more common designs. The primary mirror is curved concave. It is created typically out of thick glass that has been ground and polished to remarkable precision, which is then coated with reflective material. It can also be fashioned from a reflective metal. A second, flat mirror (typically oval-shaped) is positioned at the focal point of the primary mirror at an angle to reflect the light into an eye piece. These are the major components: the curved primary mirror, the flat reflective mirror, and the eye piece, which is typically a magnifying lens.
Why are kettles made out of iron?
Many kettles are made of metal, and a "polished" or "finished" metal kettle will often appear silver because that is the color of the metal used to make it.
How was the hubble telescope made and with what?
it was made with metal and other materials!
What type of telescope gathers radiation with a metal dish?
This best answer describes a reflecting telescope. The maximum size for a refractor on Earth is about 40 inches due to gravitational sag. Palomar's primary mirror is some 16 feet in diameter, and the Keck telescopes use several large mirrors that are computer-controlled and act as a single disk twice the size of Palomar.
Which is the Metal in reflecting telescope?
Usually aluminum. It is normally deposited as a vapour to get an incredibly smooth surface. In small home-made telescopes, they use silver.

Refracting and reflecting refer to two types of?
Astronomical telescopes are of two basic forms of construction. Reflecting types use convex lenses to magnify the image but suffer from 'chromatic abberation' where different frequencies of light are refracted uneaqaully and you end up seeing tiny spectra or rainbows of light in the image, This is overcome by a reflecting telescope which uses a concave mirror to focus light. Isaac Newton is credited with the first design and uses polished surface of a metal called speculum metal. New telescope mirrors are madeby sputtering aluminum on to the surface of a concave glass blank.There are two main types Newtonian and Cassegrain ( as found on the Hubble space telescope). refraction and reflection both refer to the way light waves 'bounce' or 'bend'. reflection is when light rays hit an object, and they 'bounce' back to the observer. if the light rays bounce off a shiny surface, they are reflected back at you and you can see the image being reflected. Refraction is when light travels from one medium to another (eg from air to water), and it changes speed. the change in speed leads to a change in the direction of the light, the direction that the light travels at changes and this is called refraction
Will metal dry if covered when wet?
Yes, metal will dry if covered wet and the temperature gets hot enough outside the cover
Why is deidaras other eye metal?
It's not a metal eye. He wears a telescope on his left eye. It's actually quite useful in battle.
What does the paint on a car do?
it covers the metal which the paint is covered .
What metal is fingernails and toe nails covered?
GOLD
What is fmj ammunition?
Full Metal Jacket. The lead core is covered by a thin jacket of metal.
What is the correct name for covering an electrode?
Covered electrodes are vital to the process of shielded metal arc welding. The covered electrode is one of four types of filler metal used when creating a joint from two pieces of metal.
