What is a periscope used for?
A periscope: An optical instrument that uses a series of prisms, lenses and mirrors to reflect images through a tube. Most often associated with submarines but they can also have other practical uses.A periscope works by using mirrors to bounce light from one mirror to the other. A normal periscope uses two mirrors at 45 degrees angles to the direction you want to see. The light bounces from one to the other and then to your eye. A periscope helps you to see around corners and over walls, they are also used on submarines so that they out and see around things.
How does a periscope work ks3?
A periscope works by using two mirrors positioned at a 45-degree angle to each other. When you look into one end of the periscope, light from the scene above the surface reflects off the first mirror and travels to the second mirror, which reflects it down to your eye. This allows you to see over obstacles or around corners without being directly in the line of sight. Periscopes are commonly used in submarines and other applications where visibility is limited.
What are the uses of a periscope?
Periscopes A periscope is a instrument of observation used for naval use or for other war-like purposes. In fact the first periscope prototype was made by Johann Gutenberg which was used to enable people to see over the heads of the crowd at the Vigintennial religious festival at Aachen. In the navy it is used in submarines to view possible threats such as enemy submarines or sea mines. Marie Davey built the first naval periscope, a simple, fixed periscope using mirrors in 1854. A periscope works 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 and then out to the person's eye.
How does a crew see the surface of water in a submarine?
Traditionally, by using a periscope to view optically above the surface. As periscopes are a weak point in a submarine - modern nuclear submarines use external cameras instead of periscopes.
What factor may prevent people from using ADSL connection?
the speed is limited to 44kbs.
Does the periscope use reflection or refraction?
Yes! Actually it is determined by how the periscope was made. The cheap ones often sold around parades and large crowds are made of cardboard and mirrors, using reflection to provide a view. More sophisticated devices in submarines and tanks will use prisms to bend the light, using refraction to change the direction of the light and provide magnification.
Can you write a sentence using the word periscope?
The submarine's periscope and radar mast are damaged.
What is the principle of a periscope?
The answer is that one mirror inside the periscope is meant to reflect the light onto the other mirror so that it goes back into your eyes. It was popularly used in World War I to see over the trenches without being a heavy target to artillery. It is also still used in submarines to see above water level whilst staying submerged.For a diagram that will (should) help, copy and paste the link below:http://www.madsci.org/posts/archives/2000-05/959444445.Eg.1.jpg
Are there any jobs that involve using a periscope?
Yea if you really want to know more about the periscope than go to a website with more knowledge and try to do more research
How does a periscope help you see closer?
A periscope uses a system of mirrors to redirect and magnify light, allowing you to see objects that are not in your direct line of sight. By using a periscope, you can see closer to objects that may be obstructed or located at a higher vantage point.
Why is it illegal to use a periscope?
Using a periscope itself is not inherently illegal; however, its use can be restricted in certain contexts, such as in areas where privacy is expected or in situations involving security and surveillance laws. For example, using a periscope to spy on someone without their consent may violate privacy laws. Additionally, in military or restricted zones, using equipment like a periscope could be subject to regulations to prevent unauthorized observation. Always check local laws and regulations regarding surveillance and privacy.
Why don't diesel powered submarines produce oxygen using electrolysis of water whilst submerged?
Modern DE submarines do have limited O2 generation capability, though the main reason it's limited is due to the enormous power consumption that electrolosis requires. Even on the surface with their diesel engines running, the electrical output just isn't enough for sustained O2 generation of any magnitude, and submerged battery operations negate using it. Nuclear Powered submarines generate more than enough power to produce enough oxygen to stay submerged indefinitely.
