There are two types of lenses- Concave and Convex. The convex ones are bulging from the center and the concave ones are bulging at the ends.
Convex=()
Concave=)(
The convex ones focus light by refracting them so the light rays meet and form a focus.
===========()>
The concave do the opposite, the light rays bend outwards [sorry for the meeting of the lines in the below pic, they do not meet but bend outwards).
===========)(<
The lens we have in our eye is a flexible, jelly type convex lens. So, the ciliary muscles which are attached to them in our eye can control the thickness of the bulging part. That helps us focus on close and far stuff.
I hope this answers your question. :)
What else can I help you with?
Do convex lenses cause light to bend?
Yes, they make light bend inwards towards a focus point.
What are two main types of lenses?
The two main types of lenses are converging lenses, which focus light rays to a focal point, and diverging lenses, which cause light rays to spread out. Converging lenses are thicker in the middle and thinner at the edges, while diverging lenses are thicker at the edges and thinner in the middle.
Why do you think lenses cause greater refraction of light?
Lenses cause greater refraction of light because they are curved and change the direction of light as it passes through. The curved shape of the lens causes the light to focus or diverge, leading to a greater bending of light rays compared to when they pass through a flat surface.
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.
What does the objective lenses do on a microscope do?
The objective lenses on a microscope collects light and brings the specimens into focus.
What does the objective lenses on the microscope do?
The objective lenses on a microscope collects light and brings the specimens into focus.
What instruments use lenses or mirriors to collect and focus light from distant objects?
Telescopes use lenses or mirrors to collect and focus light from distant objects. The lenses or mirrors help to magnify the light and form an image that can be viewed by the observer.
What is the purpose of the lenses in a camera?
Focus light onto the film
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.
Do lenses transmit and refract light?
Yes, lenses transmit light by allowing it to pass through, and they refract light by bending it as it travels through the lens. This bending of light is what allows lenses to focus and magnify images.
What do lenses in eye glasses do to the light that passes through them?
Lenses in eyeglasses bend and focus light to correct vision problems such as nearsightedness or farsightedness. They help the eye to focus light directly on the retina, allowing for clearer vision.
What lenses focus light rays?
Convex lenses, also known as converging lenses, focus light rays by bending them inward towards a single point called the focal point. This results in the formation of a real image on the opposite side of the lens.
