Which Lens has more focal length thick or thin?

Which Lens has more focal length thick or thin?

Thick lens will have shorter and consequently thin lens will have greater focal length. Because, For a thick lens, the optical path length of the light is more, than for a thin lens, thus, the bending of light will be more in case of a thicker lens. Consequently, it has a shorter focal length.

What happens to the focal length when it is cut horizontally?

Also when we cut the lens horizontally the focal length does not change, the focal length of the lens changes when the lens is cut vertically.

When convex lens is cut horizontally?

By cutting the lens horizontally,the radii of curvatures of two surfaces of the lens do not change,hence focal length f remains the same. n in the above formula is refractive index of lens- material with respect to the medium in which lens has been placed.

What will happen to the focal length of a convex lens is cut perpendicularly?

If the lens is cut along the principal axis, then there will be NO change in the focal length of the lens. But, if it is cut perpendicular to the principal axis, then the focal length will be twice the original one.

What happens if a lens is cut in half?

The focal length will remain constant if a convex lens is cut in half horizontally because the focal length of a lens depends on its two radii of curvature and the material of the lens. As no change in the material or curvature occurs, the focal length of the lens will remain constant.

What happens when a lens is cut?

Answer Expert Verified If lens is cut along the principal axis then there will be no change in the focal length of lens. but it is cut perpendicular to principal axis, then focal length will be twice the original one.

What happens when a bar magnet is cut into two pieces along its length?

When we cut along the length, pole strength of each new magnet is half the pole strength of original magnet , magnetic moment is also halved, as length remains the same.

When a magnet is cut into two pieces along its length then each piece of magnet will have?

Solution. When a magnet is cut into two pieces, then each piece behaves like an independent magnet.

Why doesn’t an iron nail behave like a magnet?

Under normal conditions, a magnetic material like iron doesn’t behave like a magnet because the domains don’t have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction. Consider a common iron nail.

Where should you not put magnets?

Below we have listed a few tech items that you should keep away from magnets and what may happen if they do come in contact with one.

1. Credit Cards. Credit and debit cards in the U.S. are often made with a magnetic stripe.
2. Computer Hard Drives.
3. Phones.
4. Televisions.
5. Pacemakers.
6. Anything with Magnetic Data.

Are magnets bad for monitors?

But LCD and LED monitors (the flat screen monitors we use today) function completely differently, so they are generally not affected by magnets. After all, your speakers use magnets to work and they don’t mess with your monitor, so the MOS is perfectly safe to use. All you need is a magnet and a CRT.

Can you destroy a hard drive with a magnet?

Yes, magnets can be used to corrupt data on a hard drive – in theory. Bringing a powerful magnet into contact with the magnetic platters could corrupt them and render the data stored on the platters unusable.
