Full-Length Mock Exam Β· Exam 4 of 10
Physics · Q 42 of 230⏱ 3:20 left

A thin converging lens has a focal length of 10 cm. An object is placed 30 cm from the lens. What is the image distance?

A.5 cm
B.7.5 cmβœ“ Correct
C.10 cm
D.15 cm
Explanation: Using the lens formula 1/f = 1/do + 1/di, with f=10 cm and do=30 cm, di = 15 cm. Physics is a high-yield OAT topic.

Imagine walking into the OAT and it feels like just another practice run. Our full-length mock exams deliver exactly that: real format, real timing, real question types across every section.

Our question bank covers every OAT section. Unlike a review book, our platform forces active recall, which is the only way the brain truly learns.

How do I remember the difference between Snell's law and the lens formula?
πŸ€–
Think of it this way: Snell's law deals with bending at an interface: n1 sin ΞΈ1 = n2 sin ΞΈ2. The lens formula relates object distance, image distance, and focal length. One is about refraction at a boundary, the other about image formation.
So if I know the focal length and object distance, I can always find the image distance?
πŸ€–
Exactly. 1/f = 1/do + 1/di is all you need for thin lenses and mirrors. Just watch your sign convention. Want a quick OAT Physics drill on this?

Stop guessing what to study. Our AI builds your entire plan around your exam date.

What is the OAT?

The Optometry Admission Test (OAT) is the standardized exam required for admission to optometry school in the United States and Canada. Administered by the Association of Schools and Colleges of Optometry (ASCO), it is one of the most important factors in optometry school applications.

The OAT consists of multiple-choice questions across four major sections: Survey of Natural Sciences (Biology, General Chemistry, Organic Chemistry), Physics, Reading Comprehension, and Quantitative Reasoning. A score of 350+ is competitive for many optometry schools.

That's what Crack the OAT is built for. Our 10 full-length OAT practice exam simulators mirror the real exam format exactly: same question types, same timing, same difficulty. By test day, you will have already sat through ten complete simulated OATs. The real thing will feel routine.

Beyond practice exams: unlimited quiz generation, unlimited flashcard decks, 100+ hours of high-yield video lessons, focused physics drills, and an AI Tutor available 24/7.
