Question

how do you see an image using a periscope?

Answer 1

A periscope is really just a couple of mirrors positioned such that you can see things from a higher perspective.



You look into an opening that points at a mirror which reflects light at a 45 degree angle from directly above.



Higher up is a second mirror which reflects light at a 45 degree angle from straight ahead to straight down.



Thus when you look through the opening at the bottom you see the light coming in from straight ahead and above.

Answer 2

The image is just reflected through two mirrors at the right angle, so that you can see what is on the 'other level'. In more complex periscopes, prisms may be used to reflect and refract the image. Check out http://en.wikipedia.org/wiki/Periscope.

Answer 3

You are actually seeing a mirror image. There is an angled mirror at the top of the periscope which reflects the image onto another angled mirror at the bottom.

Answer 4

A cheap periscope to see over crowds would work with mirrors.



A superior version would use two 90deg glass prisms!

Answer 5

if you mean how is the image percieved? the answer is the correct way round the 1st mirror would invert the image and the second mirror turnes it back up the right way

Answer 6

Have you ever tried to look at your hairdo with 2 mirrors?

That is how it works; you get a reflection of a reflection. Except it is angled instead of behind you

Answer 7

It reflects off two plane mirrors placed at rightangles in the two bends

Answer 8

Well, first you need a submarine. But the real answer is that it's all done with mirrors. Two, in fact.

Answer 9

With your eye(s) through the objective lens(es).
