What happens when you increase the diameter of a telescope?
Specifically if you increase the diameter of the main lens, or of the main mirror (depending on the type of the telescope), you'll be able to observe dimmer objects (stars, planets, etc.). Also, the telescope's resolving power (angular resolution) improves with a bigger mirror/lens. For example, with a bigger mirror/lens you'll be able to distinguish two stars that are closer together as separate objects.
What times what equals the total magnification'?
The focal length of the main optical system and the focal length of the lens forming the image.
What does L in DSLR stand for?
The "L" in DSLR stands for "single-lens reflex." It refers to the camera's design, which employs a mirror and prism system that allows the photographer to see directly through the lens and capture an accurate representation of the image.
How do you calculate microscope power?
the objective lens has the power of that lens inscribed on it
Why do lens flip and decrease the size of the object?
Because, light is transmitted by the lens
Single-lens eyes that can only distinguish light from dark?
ocelli
What is The light-gathering ability?
The light-gathering ability refers to the capacity of an optical system, such as a telescope or camera lens, to collect light from a distant object. It is determined by the size of the aperture or objective lens. A larger aperture allows more light to enter the system, resulting in brighter and more detailed images.
Define power of the lens?
It is the ability of a lens to converge or diverge a ray of light.
How will you distinguish between a convex and concave lens using a printed piece of paper?
the image formed by convex lens will converge at a point, while with a concave lens it will appear to diverge from a point.
What is the distance from a lens to one of its foci called?
The distance from the center of a lens to one of its focal points is the focal length of the lens.
After light passes through the specimen it enters what next lens system?
objective lens system
What is eyepiece is also known as?
The eyepiece can also be referred to as the lens system or lens
What body system is lens in?
Eye
What is the lens?
the lens or system of lenses in a telescope or microscope that is nearest the object being viewed
What type of lens is the lens of your eye?
The lens in the human eye is a convex lens, but it is flexible and when it is acted on by the ciliary muscle around it, the lens can be "flattened" to change the focus, or, when the muscle is relaxed, the lens can assume a more spherical shape. This is at the heart of the ability of the eye to focus on objects nearer or farther away.
Could cataracts change ability to wear old contact lens?
Yes
What is the ability to focus the image of an object at different distances on the retina?
the answer is lens. :D
