Hi there.
00:02
In this video, the concept we're going to look at is plain mirrors.
00:07
Okay, so we're going to have someone stand in a room.
00:10
There are going to be mirrors where the red wall is, where the blue wall is, and where the yellow ceiling is.
00:17
And we want to know how many images the person is going to see.
00:24
Okay, so from the red wall, there will be one.
00:32
From the blue wall, there will be one.
00:39
From the ceiling, there will be one.
00:43
So we get one from each mirror...
