### Question of the Day: MCAT Physical

A light ray traveling through a medium is reflected by a second medium at an angle of 20⁰ to the interface between the two media.  Which of the following is true?

The frequency of the light wave is greater upon reflection

The refractive index of the second medium is equal to sin(20⁰)

The refractive indices of the media must be equal

The angle of reflection is 70o

In contrast to the old MCAT, which tested students discretely on physical science topics in contexts unrelated to living systems, the revised 2015 MCAT integrates knowledge of biology, organic chemistry, inorganic chemistry, and physics in the Chemical and Physical Foundations of Biological Systems section. This section is comprised of fifty-nine questions to be answered within ninety-five minutes. It will require students to integrate scientific knowledge, demonstrate an understanding of research methods, and show an ability to apply basic statistics to the natural sciences. Whether you need MCAT tutoring in AtlantaMCAT tutoring in Houston, or MCAT tutoring in San Francisco, working one-on-one with an expert may be just the boost your studies need.

A general understanding of math concepts is fundamentally necessary for success on the Chemical and Physical Foundations of Biological Systems section. Students who score highly will be able to recognize and interpret various data plots, including linear, semi-log, and logarithmic-logarithmic representations of data. Additionally, students should show proficiency in scientific notation, significant digits, and conversions both within the metric system and between the English system and the metric system. Finally, a basic knowledge of trigonometry, primarily focused on the relationships between sine and cosine, will allow students to successfully answer questions about topics that require vector addition and subtraction. Varsity Tutors offers resources like free MCAT Physical Sciences Practice Tests to help with your self-paced study, or you may want to consider an MCAT Physical Sciences tutor.

The new MCAT focuses heavily on how inorganic chemistry and physics apply to biological systems, including bacteria, viruses, and eukaryotes. Concepts that are key to biochemistry, introductory biology, general chemistry, organic chemistry, and introductory physics all combine in this section to test how well students can integrate seemingly abstract concepts from their undergraduate courses with their understanding of processes in living systems. Two foundational concept areas figure heavily. The first foundational concept takes topics tested in biology and asks students to understand how materials are transported across membranes, how organisms interact with their environments, and how physics can be used to model how organisms respond to changes in their immediate surroundings. While many topics have been removed from this section as compared to the previous iteration of the MCAT, students will still be required to understand translational motion, force, work, energy, and equilibrium, in addition to how fluids circulate, and how gases move and exchange between environments. Additionally, chemical and physical circuits will be tested through organ systems such as the cardiovascular and nervous systems. The interaction of light and sound with living organisms will be assessed, as well as how nuclear decay and the fundamentals of atomic structure and chemical behavior relate to treating medical diseases.

In the second foundational concept area, test takers will need to have a firm grasp of how chemistry governs both molecular interactions within a cell and between groups of cells. Given that water comprises roughly seventy percent of the human body, students will need to understand how water serves as both a solvent and a buffer, how atoms interact within a molecule, and how groups of molecules interact in an intermolecular fashion. Separation chemistry and spectroscopy will also figure heavily on this section, as these methods form the foundation of many blood-based screens and complex imaging tests such as CT and MRI scans. Additionally, the principles of chemical thermodynamics and kinetics will be used to assess how well students understand how enzymes function and how Le Chatelier’s principle can be used to understand deposition and solvation of fatty particles on artery walls, causing heart disease.
