1.Why LED lamp can't light?

Reason1: Battery compartment does not pull out the insulation sheet

Reason2:Switch loose.

Reason3:Battery compartment is bad

 

2.Why can't see clear with a magnifier?

Reason: the distance between magnifier and object is not suitable?

How to use: Let magnifier close observation of objects observed object does not move, the distance between the eye and the object of constant observation, move magnifying glass between the object and the human eye moves back and forth, until the large and clear image.

You can also close magnifying glass eye as close as possible. Magnifying glass does not move, moving objects, until the large and clear image.

 

3.The relationship between magnification and diameter of lens?

Inverse relationship, that's mean more higher magnification with less diameter lens.
