Parralel light rays striking the concave lens in choice would diverge (spread apart).

Explain why a flat piece of glass does not bring light to a focus while a curved piece of glass can?
When light passes through a flat piece of glass, like a window, the light is refracted at both surfaces, but the exiting ray of light is parallel to the entering ray and hence the light's path is not really changed.
Why does a converging lens behave as a burning glass?
Convex lenses focus parallel light rays from distant sources such as the sun to a single point on the principal axis of the lens. This point is called the principal focus of the convex lens. A source such as the sun is producing enough energy to heat a substance if it is placed at the principal focus point.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
Type of microscope that uses glass lenses to focus light rays?
Optical or Light microscope
Glass objects used to bend light are called?
Well it can be any glass object to make the rays go parallel.

Is parabolic concave mirror is used in car head light?
Yes, the bulb will be kept at the focus of the parabola so that the light after refelction would go parallel and so it could cover a wide region.
Why CONCAVE MIRRORS USED IN TORCH LIGHT?
The concave mirror reflects the bulb's light, and if the bulb is at the mirror's focus, sends it out as a parallel beam.
Why don't concave lenses being light rays into focus?
Simply put, light rays do not focus light because the focus is on the wrong side of the lens, with respect to the incoming light. If you draw the ray diagram you will see that the parallel rays transmitted may appear to be coming from a focus. This is what they mean by virtual.
How does a microscope magnify?
Microscopes uses the same trick as refracting telescopes. They bend the light as it travels through the glass. In a microscope, the idea is to bend diverging lights into a parallel path, then focus that path into a light beam creating a spread out yet zoomed in image of what is on the microscope slide.
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected out through the mirror's?
focus
What glass is used in light microscope lenses?
Optical microscopes use refractive lenses, typically of glass and occasionally of plastic, to focus light into the eye or another light detector. hope it helps... kinda
What happens if light is passed through a glass slab whose sides are not parallel?
it becomes kinda prism
