Answers
Explanation:
Light travels in a zig-zag path.
A crooked path
The photon moves quickly between each water molecule, but a zigzag path between two points is slower than a straight one, so ultimately, the photon is delayed. A special type of lens can create what's known as a Bessel beam, which is a beam of light shaped into a bull's-eye pattern
A plane mirror forms a virtual imagePlane mirrors always produce virtual images, because they never focus light into a single converging point. Plane mirrors use perfect regular reflection, which creates an upright, virtual image. The mirror also keeps everything in correct proportional sizes.
.A pinhole camera can take pictures of moving objects.A pinhole camera is a simple camera. It does not have any lens . ... It is difficult to take picture of moving object with fast speed as the camera cannot focus accurately on that object.
Virtual images cannot be obtained on the screen because the image formed is from the light rays that do not meet but appear to meet when they are produced backwards. The image obtained will always be erect.
When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.
