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.

What angles would you need between two mirrors to give you nine reflected images?
At angle of 30 two mirrors will give nine reflected images.
Why semi cone angle is set between10 degree and 15 degree?
It does not need to be. It can be smaller or larger.
What angle is found on a triangle?
a 90 degree, improve this answer if you need to, im fine with it....
How do you construct a 110-degree angle with the help of a compass?
You'll also need a protractor to construct a 220 degree angle which can then be bisected by means of a compass and a straight line to form two 110 degree angles.
What degree cuts do you need to make an equal octagon from wood?
Each exterior angle is 45 degrees (interior angle = 135 degrees).
What materials do you need to make a periscope?
To make a basic periscope, you will need two small mirrors, a sturdy cardboard tube or box, scissors, tape, and a ruler. Cut the cardboard tube or box into periscope shape, attach the mirrors inside at a 45-degree angle, then use tape to secure. Adjust the mirrors until you achieve the desired reflection.
What are the materials you need to make a periscope?
To make a simple periscope, you will need two small mirrors, a sturdy cardboard tube or box, tape or glue, and a cutting tool. Cut holes at each end of the tube/box for the mirrors to fit into at a 45-degree angle. Secure the mirrors in place with tape or glue.
How do you make a periscope lets you see behind you?
To make a periscope that allows you to see behind you, you will need two small mirrors, a cardboard tube, and some tape or glue. Place the mirrors at a 45-degree angle inside each end of the tube, ensuring they reflect the view behind you. Look through one end of the periscope while holding it up to see the rear view.
How does a periscope work?
Old trench periscopes worked by using two mirrors to bounce light from one place to another. A typical periscope uses two mirrors at 45 degree angles to the direction one desires to see. The light bounces from one to the other andthen out to the persons eye.If there is an object in front of you, any nearby light source (i.e the sun, a lamp etc.) bounces straight rays of light onto the object and then into your eyes, enabling you to see it. However, if the object is not within straight lines of your eyes, the light will not find them and you will not be able to see the object (since light only travels in straight lines).But a periscope works using the laws of reflection. Reflective objects like mirrors work by bouncing light so it carries on in a straight line but alters it's route, according to the angle of the mirror to the light source. This means that if the mirror was at a 45 degree angle to the light source then it would bounce off at a perpendicular (90 degree) angle. That is how a periscope works.The important fact to note when considering a periscope is that the laws of reflection mean that the light hitting a mirror at an angle is reflected off at twice the angle of the mirror. Thus a 45 degree mirror reflects light rays through 90 degrees.Submarine PeriscopesSubmarine optical periscopes don't use mirrors due to their fragility and susceptibility to environmental conditions/changes, requiring special coatings. Instead, they use refractive prisms.The newer U.S. Virginia-class and British Astute-class boats use neither; they use a Photonics Mast, which is essentially a hi-resolution camera array that is raised above the waterline. This has many advantages, the primary one being that the Control Room need not be directly under the main sail as in all previous modern submarine designs.
Why does periscope need two mirrors?
Periscope uses two mirrors to reflect and redirect the light from the object being viewed. The first mirror at the bottom of the periscope reflects the light from the object up towards the second mirror at the top, which then reflects the light towards the viewer's eye. This arrangement allows for the object to be viewed from a different vantage point without physically moving.
How and why can you see objects through a periscope?
A periscope uses mirrors to reflect light, allowing you to see objects that are not in your direct line of sight. When you look through a periscope, you are essentially looking at the reflection of the object rather than directly at it. This design helps in situations where visibility is obstructed or when you need to remain hidden from view.
How do you make a periscope?
To make a simple periscope, you will need two small mirrors, a cardboard tube, some glue, and scissors. Cut the tube into two equal parts and attach mirrors inside each end at a 45-degree angle using glue. Align the mirrors properly so you can see reflections through the periscope.
What is degree measurement of an angle?
I need to know how to find each angle measured to the first degree. Such as: Sin B= 0.4848
What angles would you need between two mirrors to give you nine reflected images?
At angle of 30 two mirrors will give nine reflected images.
Why are two mirrors needed in a periscope?
A simple mirror will allow you to see around a corner, but to see above an object or wall, you need two mirrors aligned in a certain way. See the related link below for more information and some very helpful diagrams.
Two angles whose sum is 180 degrees?
Two 90 degree angles create a perpendicular angle. A 60 degree angle and 120 degree angle also create a 180 degree sum.
How do you identify image on inclined mirrors?
To identify an image on inclined mirrors, you need to follow the laws of reflection. The angle of incidence is equal to the angle of reflection, so you can trace the path of light rays as they reflect off the mirrors to determine the position and characteristics of the image. Remember that the image formed will appear to be the same distance behind the mirror as the object is in front of it.
