Waves, Part 1

Waves, Part 1

This is the first webinar of our two-part series on waves and will cover sound. Sound is a mechanical and a longitudinal wave.  It requires a medium, which means there is no sound in space. In this webinar, we will review commonly tested sound topics like hearing levels, Doppler effect, ultrasound, Doppler ultrasound, and resonance in sound and strings.

At a glance


Essential skills

  • Math skills for the Doppler effect, resonance frequencies, the interconversion between intensity and intensity level

  • Reading of graphs with sound waves

  • Application of sound concepts to biology and medical instrumentation


Knowledge Fundamentals

  • Basic wave equations and characteristics

  • Properties of sound waves

  • The Doppler effect

  • Intensity vs. intensity levels

  • Resonance in pipes and strings

  • Wave interference

  • Tools that use sound


On the MCAT

  • Sound is a physics topic that has overlaps in music, biology (the ear), and medical instrumentation. Sound can get quite conceptual; a common mistake students make is mixing up sound and light. Know your basics and stick to them! Sound and light are both waves but very different.


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.”
