    A Periscope is an Optical Instrument that is used to see Objects which are not at the Same level as of Observer.
    Principle of the Periscope:
    ➤ In a periscope, light from an object strikes the top Prism at 45° and bounces off at the same angle to reach the bottom prism.
    ➤ It works on the principle of total internal reflection (T.I.R.) of the light phenomenon. In Periscope, We use the totally reflecting prisms which turn the ray through 90°.
    Uses Of Periscopes :
    ➤ Periscopes uses prisms providing magnification operate on Submarines and in various fields of Science.
    ➤ People first started using Periscope in submarines to allow sailors to see above the Water.
    How this Periscope Works ?
    ➤ Inside this Periscope There are 2 Prisms that are Placed in Parallel and Facing Each Other. Also, there are 2 Mirrors that are Fixed near the Observer's Eye and on the Other End.
    ➤ The 2 Prisms in this Periscope are Placed at 45° degree angle.
    ➤According to the laws of Reflection, When a ray of light falls on a plane surface. it gets reflected at an angle equal to incident angle.
    ➤ The Reflected light falls on second prisms and is again reflected. Hence, the first prism captures the desired image and reflects surface of second Prism.
    ➤ In turn, the Second Mirror Reflects the image in a way that it can be viewed by the Observer.
