Lens Flashcards
What is F-Prime?
The F one the same side as the object
In a converging lens, how does the light ray refract when parallel?
Through the focal point on the other side of the lens
How does the light ray refract in a converging lens when going through the focal point?
Refract parallel
How does a light ray refract in a converging lens when going through the center?
It will not refract but will still keep going to the same direction
How does a light ray refract in a converging lens when going through the center?
It will not refract but will still keep going in the same direction

In a diverging lens, how does the light ray refract when parallel?
It will refrect back to F2
