Their is no document for us to look at , can you add it so i can help you
I think it’s speed will increase, if I understood it correctly
Answer:
They diverge on refraction
Explanation:
When parallel light rays strike a concave lens, they will diverge that is they spread out .
Concave lens is also known as diverging lens, which means that when parallel rays of light strike on it, the lens spreads out the light rays ( that is it diverges the rays of light) that are refracted through it.
At the middle of concave lens is thinner.
When light is passes through the lens they diverge it or spread out.
The concave lens causes light rays to bend away or diverge from its axis since the concave lens is a diverging lens.
