What is The point at which rays parallel to the optical axis reflect and meet is called?
The point at which rays parallel to the optical axis reflect and meet is called the focus of a mirror. In the context of concave mirrors, this point is where light rays converge after reflection. For convex mirrors, the focus is virtual, appearing to be located behind the mirror. The distance from the mirror's surface to the focus is known as the focal length.
What is the shape of cylineler?
A cylinder is a three-dimensional geometric shape characterized by two parallel circular bases connected by a curved surface. The axis of the cylinder runs perpendicular to the bases, and the distance between the bases is the height of the cylinder. The shape is defined by its radius, which is the distance from the center of the base to its edge. Overall, a cylinder has a smooth, curved surface and can be described as a "tube-like" structure.
Which term indicates the imaginary line that extends straight out from from the center of a reflective surface?
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
How would you find the surface area of a cylinder with circle bored out of it?
Actually, answer 1 is for the volume, not the surface area. Aside from that, there are lots of ways to bore a hole in a cylinder. If it goes from one base (a flat face) to the other (or part of the way) parallel to the axis, answer 1 is correct (for the volume). If it is not parallel to the axis, or if it is bored from the curved surface of the cylinder, it is much more complicated. Assuming, as in answer 1, that the hole goes all the way from one base to the other parallel to the axis, to get the surface area you would add the surface area of the outer cylinder to that of the hole (just the curved surface portion), and then subtract the areas of the circular holes in the two bases, each of which is pi x the radius of the hole squared. I'm assuming you know how to calculate the surface area of a cylinder. This is the area of the curved surface, which is 2 x pi x the radius x the height, plus 2 x the area of each base, which is pi x the radius squared. ========================================================== Use the formula:- Volume of a cylinder = Pi X Radius squared X Length , to find the volume of a solid cylinder. Repeat the same calculation with the same formula, to find the Volume of the cylinder of fresh air within the cylinder . Subtract the fresh air Volume from the Solid Cylinder Volume. That will be your answer . Think about your problem, then it is dead easy.
What line is parallel to the y-axis?
Any line with the equation [ x = any number ] is parallel to the y-axis.
What is the point on a concave mirror optical axis through which every light ray that travels parallel to the optical axis toward the mirror moves after being reflected?
The focus of a concave mirror is the point on its optical axis where light rays parallel to the axis converge after being reflected.
Are rays perpendicular to the principal axis of a concave mirror converge at or near the focal point?
It should be parallel. Rays "parallel to the principle axis of a concave mirror converage at or near the focal point.
What mirror is curved inwards?
A concave mirror is curved inwards, causing light rays parallel to the mirror's axis to converge at a focal point in front of the mirror. This type of mirror can be used for focusing light in various optical devices like telescopes and shaving mirrors.
What is The point at which rays parallel to the optical axis reflect and meet is called?
The point at which rays parallel to the optical axis reflect and meet is called the focus of a mirror. In the context of concave mirrors, this point is where light rays converge after reflection. For convex mirrors, the focus is virtual, appearing to be located behind the mirror. The distance from the mirror's surface to the focus is known as the focal length.
What is an optical axis?
optical axis
Is the point at which light rays parellel to the optical axis meet?
The point at which light rays parallel to the optical axis come together or appear to come together after passing through a lens is known as the focal point.
When the surface of a mirror curves like the inside of a bowl it is called a?
concave mirror
The rays parallel and close to the principal axis are called paraxial rays or not?
Yes, rays that are parallel and close to the principal axis are known as paraxial rays. These rays are used in geometrical optics to simplify calculations and analyses of optical systems.
What is the mirror that causes parallel incident rays of light to converge at the focus?
The mirror that causes parallel incident rays of light to converge at the focus is a concave mirror. This type of mirror is curved inward and has a reflective surface that causes light rays to converge towards a focal point when they strike the mirror parallel to its principal axis.
What term indicates the point where reflected light ray meet along an optical axis?
A focal point is the point where reflected light rays meet along an optical axis.
What is optic axis?
optical axis
