Draw a picture of a moving source and the waves surrounding it according to what you observed in this experiment. How does the spacing of the wave-fronts in front of the source compare to those behind it?
Imagine a small observer is positioned in front of cork in your picture above. As the cork approaches, the observer measures the wavelength of the waves passing by. How does this wavelength compare to that measured from behind the source?
Imagine that this same observer measures the frequency of the waves instead of wavelength. How does the frequency measured in front of the source appear to the observer compared to the frequency measured from behind?
How do these results help explain why a car's engine sounds different as the car approaches you compared with after it passes?
The Doppler Effect is present in light waves as well. As you will learn in the Color Lab, red light has a lower frequency than blue light. Based on your observations in this experiment, what can you speculate about the motion of a distant star that appears "red-shifted" to astrophysicists? (The light appears redder than expected.)
Cooling water flows through a jacketed reactor and is controlled by a valve. The cooling water flow rate through the jacket obeys the following relation: where the pres
In a Newton's ring set up, the gap between the glass plate and the lens is filled with a transparent liquid. If the liquid is replaced by a second liquid, the rings shrink. Which o
Steel: Steel contains iron with a small percentage of carbon added it. Iron itself is not very strong but the additions of small percentage of carbon in it decrease the ductility

Show that the displacement current flowing between the two plaes of the capacitor is similar to the conduction current utilized in charging the capacitor.
ohmmeters: The use of ohmmeters is somewhat more involved. Most importantly when measuring resistance the circuit power must be switched off, power is derived from within the i
What is the difference among dynamic strain aging and strain aging? Strain aging could be explained as " tear and normal wear " or the fatigue that is experienced under normal
Q. Illustrate how do you find the refractive index of a liquid by using total internal reflection? Answer:- Using Snell's law n (1) = (n (2) x sin angle (2)) / sin angl
