22 -- Part 2: Mirrors and Lenses
The sketch is labeled and shown below.
The one shown below is a ray diagram for the sit 10.263 m-12 uation.
The im age is enlarged, real, and inverted relative to the object.
We need to place the screen 3.8 m from the lens to be able to see what is on the internal display.
The screen needs to be close to the lens.
The internal display needs to be moved closer to the lens.
Similar to mirrors, lens images can be larger or smaller than the original objects.
To look at a tiny insect on a book page, you use a lens with a focal length of +0.0 cm.
The linear magnification equation is used.
The magnification and the height of the situation can be determined by drawing a labeled sketch.
The image is virtual according to the minus sign.
The paper was looking at the insect.
The ray diagram will be drawn horizontally, as shown below.
From the diagram, we can see that the image is upright and on the same side of the lens as the real insect.
An image is seen through a focal point.
The light hitting your eye is the same size as the object it is hitting.
You place an object 20 cm to the left of the equation.
The number is shown below.
Draw a diagram for the sit uation.
Skills for analyzing processes involving mirrors and lenses is an example.
The photographer would change the image distance to focus light on the image.
The film is 16 cm square and the image distance is 20 cm.
A person is standing 8.0 m from the camera.
The situation is sketched.
The person wanted unknowns in the sketch.

5.125 m-1 in limiting cases.
The film can fit the inverted image size of 5 cm.
The 1.9-m-tal person is close to the focal length lens.
The image is not sharp on the screen if it is 0.20 m away from the lens.
We've already talked about applications for mirrors and lens, from the magnifying glass to the digital projector.
There are three single-lens optical systems investigated in this section.
Light from a fixed can be different.
Light sensitive surface digital cameras have been replaced by an image sensor that consists of a two-dimensional array of light-sensitive elements.
You have to choose the object to focus on when taking a photo when the picture includes multiple objects at different distances.
Instead, a two-dimensional array of tiny micro-lenses is you to choose which object to focus on.
Each micro-lens has its own ter behind it.
The camera records not only how much light reaches each micro-lens, but also the direction of each ray reaching that micro-lens, since each micro lens has its own grid of pixels.
A photographer can use this camera to focus on an object after the picture has been taken, since the camera is effectively fo cusing on all objects at once.
The human eye is very similar to a digital video camera.
A human can see objects from 10 to 25 cm away.
There is a variable focal length lens system.
When the eye looks at distant objects, muscles around the lens of the eye relax, so that the image and the lens becomes less curved, increasing the focal length of any object is always on the retina.
After many hours of reading, your eyes become tired from the contraction of these muscles.
The nearest object to the eye is the shape of the lens, and it has a sharp image on objects at different distances.
objects look blurry when you swim with your eyes open.
You can see objects clearly with the retina mask.
The lens isn't the only optical element in the eye.
The rest of the eye works with the cornea to form an age on the retina.
Your eye can't bend the light passing through it to make a sharper image.
The Refractive index of water is the same as the Refractive index of the cornea.
Everything looks blurry because the eye can't procreate sharp images on the retina.
If you put air between the eye and the water, you can see better.
The inability of the eye to produce a sharp image is compensated by corrective lens.
The image of a distant with clarity but not those that are distant can be seen in a nearsighted eye.
When rays from an object pass through the eye lens, they cause an image to be formed farther back in the eye.
The virtual image is formed at the far point of the eye when the focal length of the concave lens is chosen.
The image that passes through the lens appears to come from the far point, on the retina.
The negative sign shows that the image is virtual.
A person is looking at a book or a cell phone screen.
The normal eye has an image at the far point.
The object and image are to be formed at the far point of the lens.
The number is negative.
The lens has a focal length.
Without glasses, the image of a lens for a nearsighted person is the same as the image of a distant object.
Farsighted vision can be corrected with convex lens.
The image produced by the eye lens moves forward onto the retina when it converges light from a nearby object.
The virtual image of the object at or beyond the person's point of view is produced by the lens.
The image is virtual because of the negative sign.
1>(-50 cm) is the number of diopters.
The object cave has object gative power.

The apparent size of an object as judged by the object is the same as the image's angular size.
For small angles, this is true.
Light that appears to come from the final image of the system of lenses is what a person sees if he or she looks at an object through more than one lens.
A magnifying glass has a single lens.
The enlarged image is farther away from the object than the lens is.
The object can be placed closer to the ground using the magnifying glass.
The size of the object is seen by the eye.
The object's size increases as it is brought closer to the eye.
The image is close to the point where the eye can see it.
A two-lens optical system is being analyzed.
Telescopes and microscopes use multiple lens to produce an image that becomes the object for lens 2.
The object of the first lens is the final image and calculating its magnification requires careful attention.
The image was formed by the first lens.
The image is to the right of the lens.
The image is to the left of lens 1.
The image of lens 1 is now the object for lens 2.
If the image formed by lens 1 is to the right of lens 2, the object of second lens 2 is nega tive.

The final image is smaller than the original object.

The lion's size is seen with the un in making it appear bigger than it really is.
The virtual image times smaller is negative.

A croscope magnifies tiny nearby objects.
An inverted, enlarged virtual image of the object can be seen when an observer looks through the eye piece.
Consider the magnification of the system.
The object for the eyepiece lens is the image produced by the objective lens.
The eyepiece lens acts as a magnifying glass to view the real image produced by the objec tive lens, since this ob ject is located just inside the focal point.
The magnification of the magnifying glass is determined by the angle of view.
The best optical microscopes give a magnification of about 1000.
The object for the second lens is this image.
A compound microscope has an objective lens of focal this distance to find the location of the image produced length 0.80 cm and an eyepiece of focal length 1.25 cm.
