1. the very first lens and focusing were discovered by ________in________
Answer:
Hans Lippershey in 1608.
Explanation:
The first person to apply for a patent for a telescope was Dutch eyeglass maker Hans Lippershey (or Lipperhey). In 1608, Lippershey laid claim to a device that could magnify objects three times. His telescope had a concave eyepiece aligned with a convex objective lens.
2. who invent convex lens and concave lensplease help
Convex lens was invented by Ibn
al-Haytham (Alhazen) in the 11th
century, while concave lens was
invented by René Descartes in the
17th century
answer:
His name was Benjamin franklin.
Explanation:
Realizing that a combination of convex and concave lenses in one spectacle frame would enable his aging eyes both to work close up with machinery and adjust to seeing at a distance, he worked out a way of grinding such lenses on a lathe and putting them into a frame.
3. How did Robert Hooke discover the cell in his experiment using a single lens microscope?
Answer:
Hooke had discovered plant cells -- more precisely, what Hooke saw were the cell walls in cork tissue. In fact, it was Hooke who coined the term "cells": the boxlike cells of cork reminded him of the cells of a monastery. Hooke also reported seeing similar structures in wood and in other plants.

11. what type of lens would work best to help a person who has trouble seeing small words in a newspaper
Answer:
The need for some type of vision correction is very common. Common vision defects are easy to understand, and some are simple to correct. Figure 1 illustrates two common vision defects. Nearsightedness, or myopia, is the inability to see distant objects clearly while close objects are clear. The eye overconverges the nearly parallel rays from a distant object, and the rays cross in front of the retina. More divergent rays from a close object are converged on the retina for a clear image. The distance to the farthest object that can be seen clearly is called the far point of the eye (normally infinity). Farsightedness, or hyperopia, is the inability to see close objects clearly while distant objects may be clear. A farsighted eye does not converge sufficient rays from a close object to make the rays meet on the retina. Less diverging rays from a distant object can be converged for a clear image. The distance to the closest object that can be seen clearly is called the near point of the eye (normally 25 cm).

TYPES OF LENS
Eyeglasses are used to address eyesight issues. Eyeglasses can help you see clearly at a distance or close up if you have problems seeing well. They make it easier to view items from afar more clearly and sharply.
The way light concentrates on the retina causes the majority of vision impairments. The retina is located near the optic nerve in the back of the eye. The lens of the eye transmits light to the retina, which turns it into electrical signals that are sent to the brain. The visuals we perceive are the result of this process. Eyeglasses aid in the proper placement of light on the retina.
A form of single-vision lens is a pair of reading eyeglasses. When reading, people with presbyopia frequently see objects in the distance clearly but have problems seeing the words. You can benefit from reading eyeglasses. You can typically buy them over the counter at a pharmacy or bookstore, but if you receive a prescription from a doctor, you'll get a better lens. If the prescriptions for the right and left eyes are different, over-the-counter readers are useless. Check with your eye doctor first to check if you can safely use readers before attempting to use them.

25. 3. Write a pair of sentences that use the denotative and connotative meanings of the word. Example:Len screamed when she saw the large snake staring at her.Len knew that a person who is a snake cannot be trusted.
Answer:
Denotative: The sentence describes a person named Len who saw a large snake and screamed in response.
Connotative: The sentence implies that Len was surprised and frightened by the snake's sudden appearance, and that the snake posed a threat to Len. Additionally, the sentence might suggest that Len is afraid of snakes or that she generally has a fearful disposition.
Denotative: The sentence means that Len believes that individuals who are snakes cannot be trusted. It can be interpreted that Len considers a person who is a snake to be untrustworthy.
Connotative: The sentence implies that Len may have had a negative experience with someone whom he considers a snake, leading him to generalize that all individuals who are snakes cannot be trusted. Additionally, the use of the term "snake" as a metaphor for a deceitful or untrustworthy person has a negative connotation in society. Therefore, the sentence could suggest that Len may be biased towards people who exhibit certain traits, which he associates with snakes.
