- A concave lens causes all rays to diverge.
- Concave lenses create only virtual images. After the rays are refracted, they never converge and so there will be no real images.
- All concave lens images will be upright, virtual, and diminished, and can be found between the F and the lens.
- When using the lens equation with a concave lens, the focal length must be assigned a negative value ((1/di)+(1/do)=(1/−f) ).
