What are the disadvantages of a reflecting periscope?
The main disadvantage is that it does not have the advantages of a prism periscope. 1) Glass prisms do not produce multiple reflections 2) Glass prisms do not have exposed silvered surfaces which can be damaged 3) Depending on your arranges, if not the image will not be inverted.
Why does your image appear to be behind the mirror?
I guess it is because of preception.... if your standing about a metre away from the mirror... it will appear your reflection is a metre behind the mirror
Where is your image when you look in a plane mirror?
behind you
What are characterstics of plane mirror?
The characteristics of the plane mirror include the virtual image is located behind a mirror, it is the same size as the object.
Where should the object be placed in order to produce a larger object behind a concave mirror?
The object should be necessarily be placed between the focal point of the concave mirror and the pole of the mirror to produce a larger image(not larger object) behind the concave mirror.
Why doesn't the telescope mirror in a reflecting telescope get in the way of what you are viewing?
It does, a little. But the amount of light lost by the secondary mirror blocking the primary mirror is generally a small percentage. But to avoid even that loss, some reflecting telescopes are being built with an angled primary mirror. The secondary mirror is off-axis, meaning that the secondary mirror doesn't block ANY light from the primary.
Which design has a convex primary mirror and a flat secondary mirror with the eyepiece located on the top side of the telescope tube?
The Newtonian reflector has a convex primary mirror and a flat secondary mirror with the eyepiece located on the top side of the telescope tube.
What is a reflecting telescope that used a secondary mirror to send light through a hole in the primary mirror is called?
It is called a Cassegrain. The small convex subreflector is a hyperboloid with one focus at the focus of the main mirror, and the other focus just behind the main mirror where the eyepiece is.
Is hubble space telescope a convex?
No - HSTs' primary mirror is a Cassegrain Reflector of Ritchey-Chrétien design, which contains a hyperbolic primary/secondary mirror.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
How do you remove the side view mirror housing on a 1997 SL?
pull off plastic inside directly behind the mirror it just pulls off and you will expose the bolts to remove the mirror.
What reflecting telescope has a focus which results from a single secondary mirror and which forms through a hole in the primary mirror?
are you doing your science homework?
How many centimeters is the diameter of the Hubble telescope's mirror?
The primary mirror of the HST has a diameter of 2.4 m; the secondary mirror measures 30 cm in diameter.
What is a reflecting telescope that uses a secondary mirror to send light through a hole in the primary mirror called?
That is called a Cassegrain. The main mirror is a paraboloid which focusses the light from a star down to a point, then the secondary small mirror is a hyperboloid with one focus that coincides with the focus of the main mirror, and the other focus is behind the main mirror, where the eyepiece is. This arrangement is common in radio telescopes as a way of reducing radio noise picked up from the 'hot' ground which is at approximately 260 degrees Kelvin or more.
What are the uses of a serrurier?
Serrurier is used in telescope tube assembly. Created in 1935 by engineer Mark serrurier.It supports the primary objective mirror and the secondary mirror.
What is a primary mirror?
a primary mirror is the main mirror
Is aluminum a secondary or primary source of light?
Aluminium is not normally a source of light. I suppose if you made a large mirror out of it you could turn that into a secondary source.
