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.
Some disadvantages of a reflecting periscope are that it can introduce image distortion or reduction in image quality due to multiple reflections within the periscope. It also requires precise alignment and calibration to ensure accurate image transmission. Additionally, the use of mirrors in the periscope can lead to image degradation or loss of light transmission.

One disadvantage of a reflecting telescope is the typical style in use today, the Newtonian style reflector, utilizes a secondary mirror to bounce the focused light from the primary mirror out the side of the tube for focusing (otherwise the viewer's head would be in the light path). Both the secondary mirror and the support apparatus for it - usually called a 'spider' assembly (or sometimes an optical window) - cause diffraction as they are in the light path for the primary mirror. This can cause a loss of contrast and 'spikes' to appear on brighter stars and/or planetary images in the eyepiece. The larger the secondary mirror and thicker the spider vanes, the more loss of contrast occurs; conversely, the smaller the secondary and thinner the vanes, the less loss of contrast there is. Typically a secondary mirror that is 20% of the diameter of the primary mirror is consider to incur minimal contrast loss.

What is a periscope mirror called?
A periscope mirror is referred to as a "prism" or a "reflecting prism." It is the component used within a periscope to reflect light at a 90-degree angle, allowing for the viewing of objects that are not in direct line of sight.
A periscope is an instrument for observation over around or through an obstacle. explain how light travels in a periscope. diagram the light rays as these pass through the periscope.?
In a periscope, light enters one end and undergoes multiple reflections off mirrors to change its path in order to see around obstacles. Light travels through the periscope by reflecting off two mirrors placed at 45-degree angles, allowing it to change direction and reach the observer's eye at the other end of the periscope. By reflecting off the first mirror, bending downward to the second mirror, and reflecting again towards the eyepiece, the light enables viewing over an obstacle without being obstructed.
How does the length of the periscope affect the size of the image seen?
The length of the periscope does not affect the size of the image seen. The size of the image is determined by the mirrors inside the periscope that reflect the light, not the length of the periscope itself.
How does a periscope work to refract light?
A periscope uses a system of mirrors to reflect and refract light in order to allow an observer to see objects that are not in direct line of sight. Light enters one end of the periscope, gets reflected by mirrors inside, and then refracted at the eyepiece to reach the observer's eye, providing a view of objects at a different height or distance.
How many mirrors are there in a periscope?
A periscope typically contains two mirrors - one at each end of a hollow tube. The first mirror at the top of the periscope reflects the image into the tube, and the second mirror at the bottom of the periscope reflects the image out to the viewer's eye.

Does a periscope work to refract light?
Periscopes work by reflecting light, not refracting it. Light enters the top of the periscope and is reflected through 90 degrees by either a plane mirror or a right angled prism (TIR) and travels down the tube where it is reflected again along the eyepiece to the eye.
What are the disadvantages of video conference?
You cannot see what is going on beyond the scene that the camera is reflecting.

What is the antonym for periscope?
The antonym for "periscope" is "submerge." A periscope is a device used to see above water, while submerge means to go underwater or be completely covered by something.
