Answer ALL questions. Please fully define your equations and provide complete explanations and I will give you a thumbs up and a good comment! Thank you!

1. Explain what the “focal length” of a lens is.

2. What is the difference between converging and diverging lenses?

3. What is the relationship between the object distance and the image distance for a lens?

Answer #1

Two thin lenses with a focal length of magnitude 10.0 cm , the
first diverging and the second converging, are located 7.50 cm
apart. An object 3.00 mm tall is placed 16.7 cm to the left of the
first (diverging) lens.
How far from this first lens is the final image formed?
Is the final image real or virtual?
What is the height of the final image?
Is it upright or inverted?
Thank you!!

The uncorrected eye.
For the following questions, assume that the distance between the
eye lens and the retina is 1.70 cm. In other words, since the image
is always formed on the retina, the distance between the lens and
the image is always 1.70 cm. Also note that, as is seen in the ray
diagram, since the eye lens is converging and the image is on the
opposite side of the lens compared to the object, the image is
always...

Hi. Please answer 1-4 and show work. Thank you! :)
1. An object is placed along the axis of a concave mirror halfway
between its focus and center. In terms of the focal length f, how
far from the mirror is the image?
a. 2f/3
b. 3f/2
c. 2f
d. 3f
2. An object is placed 10cm from a concave mirror; the image
