It slows the light down
The difference between the two is that once the light passes through the concave lens it diverges, and the rays are refracted outward, and never meet a focal point. Then there is the parallel light rays that bounce off the curved surface of a concave mirror and then meet a single point ( focal point).
Light is scattered as it passes through a prism.
What type of image can a concave lens form
Opaque - light does not pass through. Transparent - all light passes through. Translucent - some light passes through.
It slows the light down
When a beam of light passes through a colloidal solution it scatters because of tyndall effect.
the Tyndall effect
Light travelling through a concave lens will spread out. In most optical systems that use a concave lens, such as a telescope that needs to magnify the focal plane image, this is a desirable effect.

light passes in straight line
What type of image can a concave lens form
You see a rainbow in the sky because of the interaction of sunlight with water droplets in the air. When sunlight passes through the water droplets, it is refracted (bent) and dispersed, creating the different colors of the rainbow.
Opaque - light does not pass through. Transparent - all light passes through. Translucent - some light passes through.
Light usually passes through a transparent object. Similarly, light passes through the translucent objects but people cannot see through it.
