Principle:

01 periscope: It is interesting to look at the scene outside with a periscope. In the reflection phenomenon, the reflection angle is equal to the incident angle and the reflected light and the incident light are on both sides of the normal. Reflected light, incident light and normal are in one plane.

02 telescope: The telescope contains two lens-objective lens and eyepiece. The objective lens converges the light from a distant scene into a reverse-reduced real image behind it, which is equivalent to moving the distant scene to the imaged position and magnifying the image through the eyepiece.

Note: You have two options. The price is for 1 set. Don't put the periscope into the water so as not to transform.
