Photoelectric Effect

Photoelectric Effect

In 1921, Einstein was awarded the Nobel Prize for Physics for discovering the photoelectric effect. Since then, it has commonly appeared in intro physics classes and (possibly) on every C/P section of the MCAT. While understanding the concepts for this effect is not too challenging, students often find themselves lost with the math and units. Join us for this high yield webinar on the most tested MCAT C/P equation and concept.

At a glance


Essential skills

  • Calculate with E = hf

  • Handle scientific notation and common unit conversions

  • Calculate maximum KE of a photoelectron

  • Apply the photoelectric effect concepts to experimental set up and graphs


Knowledge Fundamentals

  • The properties of light and the E/M spectrum

  • E = hf

  • Frequency vs intensity

  • How work function incorporates into the photoelectric effect

  • How the photoelectric effect bridges atomic chemistry and waves concepts in physics


On the MCAT

  • The photoelectric effect is consistently tested on the C/P section and you shouldn't be surprised to see one or more passages about it on your test. The test writers also know that E = hf calculations can slow students down, so they like to use them to disorient you!

  • No need to memorize constants like h for the test


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
