Item Descriptions:
You can see that the image reflected on the screen varies depending on the distance from the light source to the lens.
● The position on the base is marked so that the position of the focal length and the position twice the focal length are clearly shown, and since the notation of the full size of the light source is written on the screen, the position of the light source and the size of the image
Relationships can be easily confirmed.
● The light source uses a light bulb that simulates a candle flame, and you can safely perform experiments according to textbooks.
You can also check that the left and right of the real image are reversed by coloring it with a felt pen etc. in the flame part.
● Because it is only inserting parts, it will not take time to assemble.
◎ Outside twice the focal length ... Outside upside down and reflections smaller.
◎ Double the focal length ... It flips upside down and reflects in the same size as the real thing.
◎ Outside the focal length, inside 2 times ... turn upside down and look larger than the real thing.
