What else can I help you with?
What is the point directly above the focus?
The point directly above the focus is the vertex of the parabola. The focus is a specific point on the axis of symmetry of the parabola, and the vertex is the point on the parabola that is closest to the focus.
What do you mean by far point and near point of human eye and what is their values of normal eye?
Far point- it is the range till where our eyes can see and in a normal human being it is infinity.Near point- it is the nearest possible distance from our eye till which we can see an object clearly. it is 25 cm in human.
Can you see cuba from jamaica?
It is not possible to see Cuba from Jamaica as they are geographically separated by the Caribbean Sea, which is about 90 miles wide at its closest point.
Is the equator the closest point to the sun?
no
What does The central point encompasses?
The central point encompasses the main idea or key concept of a topic or discussion. It serves as the focal point around which other information or details revolve, providing a clear focus for understanding and interpretation.
Are Scotland and Ireland near each other?
Yes. They are separated by sea but on a clear day at their closest point it is possible to see Scotland from Ireland.
What is the point directly above the focus?
The point directly above the focus is the vertex of the parabola. The focus is a specific point on the axis of symmetry of the parabola, and the vertex is the point on the parabola that is closest to the focus.
What is the extreme point on a parabola?
The highest or lowest point of the parabola, it is the point that is closest to the focus. The extreme point lies on the axis of symmetry
What is the extreme point of a parabola?
The extreme point it the highest or lowest point of the parabola (depending if it is concave downwards or upwards). It is the point of the parabola tat is closest to the focus. the extreme point lies on the axis of symmetry.
Is it possible to focus your eyes on one point while looking at both of your eyes in the mirror?
No
How many foci does a parabola have?
A parabola has a single focus point. There is a line running perpendicular to the axis of symmetry of the parabola called the directrix. A line running from the focus to a point on the parabola is going to have the same distance as from the point on the parabola to the closest point of the directrix. In theory you could look at a parabola as being an ellipse with one focus at infinity, but that really doesn't help any. ■
What do you mean by far point and near point of human eye and what is their values of normal eye?
Far point- it is the range till where our eyes can see and in a normal human being it is infinity.Near point- it is the nearest possible distance from our eye till which we can see an object clearly. it is 25 cm in human.
What is the significance of the near point of eye in determining the optimal distance for reading and other close-up activities?
The near point of the eye is the closest distance at which an object can be seen clearly. It is significant in determining the optimal distance for reading and other close-up activities because it helps to identify the point at which the eye can focus most comfortably and efficiently. This distance is important for preventing eye strain and maintaining clear vision during tasks that require close focus, such as reading or using electronic devices.
How do cell phone cameras focus to capture clear and sharp images?
Cell phone cameras focus by adjusting the distance between the lens and the image sensor to ensure that the light rays converge at a single point, creating a clear and sharp image.
What is the near point of vision?
The near point of vision increases with age because the elesticity of the lens decreases as we get older.near pointthe nearest point of clear vision, the absolute near p. being that for either eye alone with accommodation relaxed, and the relative near p. that for both eyes with the employment of accommodation
What point in a planets oribits is closest to the sun?
perihelion is the point in a planets orbit when it is closest to the sun
How does a lens focus light to create clear and sharp images?
A lens focuses light by bending and refracting it, bringing the rays together at a single point called the focal point. This process creates a clear and sharp image by ensuring that light rays from each point on the object converge at the corresponding point on the image.
