In actuality, there are two focal points for every lens, the same distance from the lens, on opposite sides. The distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths.

Is AP Physics 2 harder than C?
Both AP Physics C courses are calculus-based, meaning you should have already taken calculus or concurrently be taking calculus while you take either AP Physics C course. This is the main factor that makes Physics C more challenging than Physics 1 and Physics 2.
Is a 2 on the AP Physics 1 exam good?
Scoring Criteria According to Collegeboard, a 2 on the AP® Physics 1 exam suggests to colleges that you are “possibly qualified” but that there are some gaps in your knowledge of the curriculum.
When the focal length becomes negative?
(ii) The negative focal length of a lens indicates that it is a concave lens.
Is focal length positive or negative in concave lens?
A concave lens is a diverging lens, so it will always have a negative focal length. Therefore, the power of a concave lens is also negative.

Is AP chem or AP Physics harder?
Based on College Board pass rates, AP Physics 1 is more difficult than AP Chemistry. That said, AP Chemistry is not far behind — AP Physics 1 has a pass rate of about 52% while AP Chemistry has a pass rate of 56%.
Is a 4 on AP Physics 2 GOOD?
Earning a 3, 4, or 5 is generally accepted as scoring well on an AP® exam. As reported by the College Board, a 3 is ‘qualified,’ a 4 ‘well qualified,’ and a 5 ‘extremely well qualified.
Do colleges like AP Physics?
Like Mechanics, most colleges will accept a satisfactory score on the AP Physics C: Electricity & Magnetism exam in place of an introductory college-level physics course. Check your target colleges’ websites for the exact score you need to aim for.
Is Physics 1 or 2 harder?
Physics 2 is certainly harder than physics 1 because it is more abstract, has more irregular calculations, and has more challenging topics. Physics 1 is easier because it has topics that are easier to visualize and we are more familiar with.
Is focal length positive or negative in convex lens?
both convex mirror and convex lens have negative focal length.
Which lens has a negative focal length?
Convex lens has negative focal length and concave lens has a positive focal length.
Can the lens power be negative?
Yes, the power of a lens can be negative. The focal length of a concave lens with a virtual focus is negative, and hence the power is negative.
Is focal length negative in convex lens?
Focal length of convex lens is positive.
Is concave lens always negative?
The object distance is always negative. For a concave lens, the focal length is also always negative. In this case of a concave lens, u and f have negative non-zero values.
Why focus of convex lens is positive?
Focal length of the convex lens is positive because light ray parllel to principal axis passes through focus on the other side of the lens.
What AP exam has the lowest pass rate?
AP Physics 1 Physics 1 has the lowest pass rate of any AP exam (42.1%) along with one of the lowest percentages of students scoring a 5 (just 6.9%). Physics 1 is an algebra-based physics class that explores topics such as Newtonian mechanics, simple circuits, and mechanical waves.
Is 4 APs too much?
Unless you’re applying to the most selective universities, 4 to 5 AP courses over your high school years is more than enough. For students applying to the most selective colleges, you might need 7–12. But even so, taking 4 AP courses in a year can be extremely challenging.
Is AP Physics 2 hard?
In 2016, the AP Physics 2 exam remained a difficult one to master, although Physics 1 had the lowest pass rate of any AP exam. 61.3% of students taking the AP Physics 2 exam passed (by receiving a score of three or above), but only 9.5% received the highest score of five.
What is the most popular AP class?
AP English Language and Composition is by far the most popular AP test, with over half a million students taking the exam in 2021.
How many AP classes should I take for Harvard?
Going up the selectivity chain, the average at Harvard is eight AP classes. To be competitive at some of the most highly selective colleges in the country, 8-12 AP courses may be the sweet spot amount, assuming the student can handle that level of rigor.
Should I take AP physics if I want to be a doctor?
Science Classes If your school offers them, taking AP Biology and/or AP Chemistry are two of the best classes you can take to help you be prepared, since you’ll be taking multiple biology and chemistry classes in college. AP Physics is also useful since pretty much all med schools have a physics requirement as well.
Does APs self study look good?
No, it doesn’t look as good. Self-studying APs isn’t really as helpful to college admissions as people here make it out to be. Colleges are much more concerned with your grades in AP classes since it gives them a better picture of a certain student.
How difficult is AP Physics?
AP® Physics will most likely be a very challenging course, but it will also be very rewarding. If you can score high enough, you will be able to save time and money by receiving credit for physics classes while you are still in high school.
