Why are mirrors placed at 45 degree angle in a periscope?
so that light bounces off one to the other lets say you want to look up to see what is in front of you. If you look up at a angle that is completely vertical, that degree measurement would be 90*. the horizontal plane would be 0*. the angle in-between the two is 45*. so if you look up, at 90* at a mirror that is placed at 45* then you will see what ever is in the mirror at 0* in front of the mirror. If the mirror was at lets say 75* you would look up at the sky, if the angle was at 30* you would look at the water.
What happens when two mirrors face each other in a certain angle?
Depending on the angle between them, you will get multiple reflections of any object between the mirrors. If the mirrors meet at an angle of x degrees, an object placed between them should generate a maximum of (360/n) - 1 images. Parallel mirrors should, on that basis, produce an infinite number of images but because of microscopic flaws in the mirror, absorption, internal refraction etc, the images will degrade more or less exponentially.
What are images formed when two mirrors are kept at an angle of 72 degree?
Reflections and reflections of reflections.
How many images are formed when the two mirrors are inclined at an angle of 80 degree?
4.5 or 3.5 The number is five.
When two plane mirrors are placed at an angle of 60 degrees to each other the images formed are?
Virtual images.
How is light redirected in a periscope?
With mirrors. A simple periscope can be constructed out of a vertical tube with mirrors placed at a 45-degree angle at the top and bottom of the tube.
How much mirrors does a kaleidoscope have?
It has two mirrors set at an angle of 60o.
How periscope is made?
A Periscope is a type of observation material used during World War I. It is made up of two mirrors in parallel position with an angle of 45 degree placed inside a case. Periscope can also be seen on submarines and other military equipment.
How does light travel through a periscope?
Simply a periscope is a tube with two right angles top and bottom. In the right angle section two mirrors are set at a 45 degree angle. Thus light coming in the top horizontal tube hits the mirror and is reflected down the vertical bit of the tube where it hits the second mirror and is reflected out horizontally again.
How mirrors are placed in a periscope?
There are no mirrors in a periscope - they use prisms. But you could use two at 45 degrees to the object and observer, parallel to one another
How the use of mirrors helps the user of a periscope see above the water surface?
The mirrors are fitted at 45 degree angles in a periscope in the opposite directions. when you see through the periscope, the image gets reflected.
What is a periscope in detail?
A periscope is an optical instrument that uses a system of prisms, lenses, or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye.
How has the development of a periscope changed over the years?
the mirrors of a periscope have gotten bigger and are easier to see out of.
How many mirrors are in submarine?
If you mean in the periscope, two.
How has the periscope developed over the years?
they use diffrent mirrors
What is the number of mirrors used to make a simple periscope?
2.
Why does a periscope need two mirrors at a 45 degree angle?
Because the bottem mirror which is set and 45 degrees the light bounces off of and goes up at exactly 90 degrees that light then bounces off the top mirror and out a hole for you to look through.
