Convex lenses refract light rays in towards a central point.

Yes.
Yes, it does refract light.
No, opaque substances can NOT refract light. It is impossible to refract light if it is blocking it's path.
Refract
a prism can be used to refract wight light
Yes.
Cameras do not refract light, lenses do. Refraction occurs whenever light passes from one medium to another, so it is not something that only occurs with lenses.
A prism refracts light, and a mirror reflects light.
its a concave lens(:
yes
water is one
Mirrors don't refract, they reflect. All lenses, on the other hand, refract (bend) the light. All cameras have lenses, to focus the image; same for eyeglasses. Some telescopes have lenses, but others are collections of mirrors. Note that some few optical elements are lenses and mirrors - like prescription sunglasses with mirror coating.
A microscope contains one or more glass lenses that refract light that passes through them. Both microscopes and magnifying glasses utilize convex lenses.
That's how lenses work. If the light didn't refract, there would be no value to having a lens.
They refract the light before it enters your eye the precise amount it needs adjusting to make the light hit your retina in the correct position.
Objects that refract light include lenses, prisms, and water droplets. When light passes through these objects, its path is bent or altered due to the change in medium or the different angles of the surfaces.
Yes, it does refract light.
