MCAT Physics Questions and answers
What are the unit equivalents for volts (V)? - **🔰 VERIFIED ANSWERS🔰 ✔✔J/C



What are the units for an electric field? - **🔰 VERIFIED ANSWERS🔰 ✔✔N/C or V/m



What are the unit equivalents for joules (J)? - **🔰 VERIFIED ANSWERS🔰
✔✔Kg*m^2*s^-2 or N*m



How do you calculate frequency when given wavelength? - **🔰 VERIFIED ANSWERS🔰
✔✔Frequency is speed of light (c) divided by wavelength: f = c/λ



If harmonics intersect at y=0, what terms best describes their level of displacement? - **🔰
VERIFIED ANSWERS🔰 ✔✔They are at zero displacement



How do you calculate frequency when given the period (T) - **🔰 VERIFIED ANSWERS🔰
✔✔Frequency is equal to the inverse of the period: f = 1/T



As harmonic levels increase, what happens to the frequency and the wavelength? - **🔰
VERIFIED ANSWERS🔰 ✔✔As harmonic levels increase, frequency will increase. Since
frequency is inverse to wavelength, wavelength will decrease.



What is the Doppler equation for wavelength? What does each variable represent? - **🔰
VERIFIED ANSWERS🔰 ✔✔The Doppler equation is: Δλ/λ = v/c. v represents the relative
velocity between objects. c represents the speed of light. Δλ represents the change in
wavelength due to the Doppler effect. λ represents the initial wavelength of the signal.



What is the Doppler equation for frequency? What does each variable represent? - **🔰
VERIFIED ANSWERS🔰 ✔✔The Doppler equation is Δf/f = -v/c. v represents the relative
velocity between the objects. c represents the speed of the sound wave. f represents the
initial frequency of the wave. Δf represents the frequency shift.
