Simply put, light rays do not focus light because the focus is on the wrong side of the lens, with respect to the incoming light. If you draw the ray diagram you will see that the parallel rays transmitted may appear to be coming from a focus. This is what they mean by virtual.
What else can I help you with?
Do glasses have concave lenses?
Yes, glasses can have concave lenses. Concave lenses are used to correct nearsightedness, as they diverge light rays before they reach the eye, helping focus the image properly on the retina.
Does someone who has myopic need concave or convex lenses?
A person with myopia (nearsightedness) needs concave lenses to correct their vision. Concave lenses diverge light before it enters the eye, helping to focus the image correctly on the retina and improve vision for nearsighted individuals.
How are concave and convex lenses different?
Convex bulges outward (thicker in the center than the edge)Concave bulges inward (thinner in the center than the edge)Convex lenses magnify when you look through then, concave lenses make things look smaller.You can focus a distant object to a point with a convex lens (the image will be upside down).
Do cameras have concave or convex lenses?
Cameras typically use convex lenses to focus light onto the image sensor or film. Concave lenses are not commonly used in cameras because they cause light to diverge rather than converge, making them unsuitable for image formation.
How are concave and convex lenses similar?
Concave and convex lenses both have curved surfaces that refract light. They are used to focus or diverge light rays depending on their shape and can be used in various optical devices such as cameras, telescopes, and eyeglasses.
How are convex lenses and concave lenses the same?
They are not the same. Convex lens bulge outward, and concave lenses go in ward. Convex lenses focus light, and concave lenses spread light out.
Do glasses have concave lenses?
Yes, glasses can have concave lenses. Concave lenses are used to correct nearsightedness, as they diverge light rays before they reach the eye, helping focus the image properly on the retina.
Do microscopes use concave or convex lenses?
Microscopes primarily use convex lenses. Convex lenses converge light rays to create a magnified image. There are also compound microscopes that incorporate both convex and concave lenses to enhance the quality of the image.
Why do concave lenses help if you have mypoia?
Concave lenses are used to correct myopia, or nearsightedness, by diverging light rays before they enter the eye. This adjustment allows the light to focus further back on the retina rather than in front of it, which is where it would typically focus for someone with myopia. By spreading the light rays outward, concave lenses help improve distance vision for those affected by this condition.
Does someone who has myopic need concave or convex lenses?
A person with myopia (nearsightedness) needs concave lenses to correct their vision. Concave lenses diverge light before it enters the eye, helping to focus the image correctly on the retina and improve vision for nearsighted individuals.
What lenses refract light outward and are thinner in the middle?

Do near sighted people wear concave or convex lenses?
Near sighted people wear concave lenses to correct their vision. These lenses help to diverge light rays before they reach the eye, which helps to focus the images properly on the retina.
What are the use of concave?
Concave lenses are used todiverge rays of light.
Is a lenses in glasses concave or convex?
Lenses can be concave or convex depending on their shape. Concave lenses curve inward and are thinner in the center, causing light to diverge. Convex lenses curve outward and are thicker in the center, causing light to converge. Glasses can have either concave or convex lenses, depending on what vision correction is needed.
