What do lenses do to light rays?
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
What kind of images does a convex lens produce?
Convex lenses form real images and concave lenses form virtual images. But there is one case in which convex lens also forms virtual images. This is when object is placed between Principal Focus "F" and Optical Centre "O"
Why will a diverging lens never produce a real image?
A diverging lens can only produce a virtual image, because the light passing through a diverging lens never converges to a point. The virtual image produced by a diverging lens is always right-side-up and smaller than the original object. The image and the object viewed are always on the same side of the lens. Diverging lenses are used as viewfinders in cameras.
How are convex and concave lenses different from each other?
Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
What is an instrument that uses a combination of lenses to produce enlarged images of tiny objects?
An instrument that uses a combination of lenses to produce enlarged images of tiny objects is a microscope.
Lenses may produce real or virtial lenses?
Lenses is known as a virtual lenses. This is something that you put on the eye to help see better.
Why are lenses and mirrors used in optical tools?
Because they converge, diverge and reflect light.
What do lenses do to light rays?
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
What do converging lenses do to light rays?
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
Does concave lens produce a real image?
Because when you extend the light rays, they diverge and never meet. so you must always extend the light rays back behind the object, this will always result in the image being upright and erect. Meaning it will always be virtual, never real.
What kind of images does a convex lens produce?
Convex lenses form real images and concave lenses form virtual images. But there is one case in which convex lens also forms virtual images. This is when object is placed between Principal Focus "F" and Optical Centre "O"
What kind of lens can be used to produce a virtual image?
Convex lens produces both real and virtual images. But concave lens produces only virtual images for real objects. If object is virtual then real image could be produced by a concave lens.
Why will a diverging lens never produce a real image?
A diverging lens can only produce a virtual image, because the light passing through a diverging lens never converges to a point. The virtual image produced by a diverging lens is always right-side-up and smaller than the original object. The image and the object viewed are always on the same side of the lens. Diverging lenses are used as viewfinders in cameras.
How are convex and concave lenses different from each other?
Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
Does a camera use a diverging lens?
All cameras have converging lenses instead of diverging because they need a real image and not a virtual one to capture a photo.
Which of these statements is falseLenses may produce real or virtual images.Lenses transmit and refract light.Lenses may make objects appear larger or smaller.Lenses may be planar, convex, or concave?
Lenses may be planar, convex, or concave.
What is an instrument that use a combination of lenses to produce enlarged images of tiny objects?
An instrument that uses a combination of lenses to produce enlarged images of tiny objects is a microscope.
