What is the working principle of the periscope?
A periscope is a useful example of the law of reflection at work. It’s important that your mirrors are placed at a 45° angle, because light always reflects away from a mirror at the same angle that it hits it. In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle.
What is periscope describe its working with diagram?
A periscope works on the principle of reflection of light from one plane mirror placed at an angle(450) parallel to other plane mirror. Diagram shows the position of mirrors and light rays. In the figure a and b are the positions of mirror at an angle of 450.
How do you make a periscope stem?
Follow these steps…
- Cut along all the lines of the template.
- Take one half of the template, roll it into a tube and secure it with sticky tape.
- Take the other half of the template, wrap it around the first half and secure it with tape.
- Slot the mirrors into each end and tape them down.
- Now look through your periscope.
What is the principle behind the working of periscope and kaleidoscope?
The basic principles used in the kaleidoscope are the law of reflection, and white light is a combination of VIBGYOR. When the white light hits the surface of the mirror, it gets reflected at an angle such that the angle of incidence is equal to the angle of reflection.
Which light phenomenon takes place in periscope?
Reflection of light
Reflection of light is the natural phenomenon based on which a simple periscope works.
What periscope means?
Definition of periscope : a tubular optical instrument containing lenses and mirrors by which an observer obtains an otherwise obstructed field of view.
Which are the two properties of light that enables the periscope work?
The correct answer is Reflection. The property of reflection is used in making a periscope.
Which type of mirror is used in periscope?
Plane mirror
| Device | Type of mirror |
|---|---|
| Periscope | Plane mirror |
| Floodlights | Concave mirror |
| Shaving mirror | Concave mirror |
| Kaleidoscope | Plane mirror |
Which scientific phenomenon is related to the working of periscope?
Reflection of light is the natural phenomenon based on which a simple periscope works.
What kind of mirror is used in periscope?
Which lens use in periscope?
The periscope lens itself uses a folded 4x telephoto lens combined with a 48-megapixel sensor, which can swap between 4x and 10x zoom. Samsung’s zoom feature is technically a hybrid option because it uses some sensor cropping for the 10x zoom.
