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.)
(a) Potential energy : An electron operates some potential energy due to this found in the field of nucleus potential energy of electron in nth orbit of radius rn is given by
An approximate equation for the velocity distribution in a rectangular channel with turbulent flow is where umax is the velocity at the surface, y is the distance from the
What do you mean by Moseley's law? Explain briefly its importance. Explain the origin of X-ray spectra. Describe continuous and characteristic x-ray spectrum.
Ohm's law (G. Ohm; 1827): The ratio of the potential difference among the ends of a conductor to the current passing through it is constant; the constant of proportionality is
It is the ratio of the internal electric field induced by the charges on the surface on the dielectric when an external field applied to the polarization of the dielectric.
