Instead of parallel rays, consider the light as a wave front. It leaves the source in a spherical wavefront. At a certain distance the sphere is so large and the curvature of the wavefront becomes so small that it can be considered locally flat, and behaves optically as though it were flat. At that point, the flat wave front is equivalent to parallel rays (which are perpendicular to the front).
What else can I help you with?
An image of a distant object caused by refraction of light is called a?
a mirage
Is Pluto really the most distant solar system object?
Sedna is the most distant solar system object discovered so far. It is about three times farther away than Pluto currently is. Because it is so far away, scientists are not sure if it has enough mass to be classified as a dwarf planet.
What direction is the force of friction compared to the surface of a slope?
Parallel to the surface of the slope and opposite to the movement of an object on the slope. Parallel to the surface of the slope and up-slope, in the case of an object resting in place on the slope.
Why you can not differentiate between near and distant Star by naked eyes?
You have two eyes, away from each by about 6 cm. The object placed nearby makes a larger angle to both eyes as compared to distant object. From that angle, you make out the distance of the object from you. Stars are too far away for human eyes (or any animal eyes, for that purpose.) to make smaller or bigger angle. They all make the smallest possible angle witch can be recognized by naked eyes and so you can not differentiate between near or distant star. All of them are distant objects for human eyes.
Marked with parallel scratches or grooves?
i believe that you are talking about glacial striations
True or false when you come closer to a distant object with a telescope the rays become less parallel?
True. When you come closer to a distant object with a telescope, the rays of light entering the telescope become less parallel as the object appears closer, and the lens or mirror in the telescope needs to adjust the focal length to focus properly on the object.
Why is the image of a distant object formed by a convex lens is real?
Rays coming from distant object parallel to principal axis after passing through the lense converge at focus hence forming a real imageRegardsRakesh Bauraihttp://sankrantee.blogspot.com
Why is it probe a distant past is extremely difficult?

When focusing on a distant object is the lens more concave?
When focusing on a distant object, the lens is more convex. The convex lens bends light inward and converges it at a focal point to form a sharp image of a distant object.
What are 5 object parallel lines?
nothing there was ))))) this is parallel line
What happens when the ciliary muscles view a distant object?
When the ciliary muscles view a distant object, they relax. This causes the suspensory ligaments to pull tight, which flattens the lens of the eye. As a result, the eye is able to focus on the distant object by decreasing its refractive power.
Why is sedna important to the solar system?
it is the most distant object object known
What are the advantages and disadvantages of parallel parking?
Parallel is hard for some people and easy for some people.
What is a false image of a distant object?
It is known as a mirage.
What is the most distant object to orbit the sun?
uranus
When you see distant object your focal distance increases or decreases?
When you see a distant object, your focal distance increases. This means that your eyes adjust in order to focus on the object that is far away, by lengthening the shape of the lens to bring the object into focus.
