Ah! I see. Thanks.
But what about the interpretation of Doppler...
In this case, is it true that photons from an approaching emitter arrive with more energy (presumably the emitter's kinetic energy) than photons from a stationary emitter, which arrive with more energy than a receding emitter??
Doppler in depth...
thanks, folks. can we think of the approaching emitter as (sort of) "hurrying" the photons along-- as if pushing-- which compresses the wavelength, increases the frequency, and thus adds energy (E=hf)? Which is the reason we call the effect a blueshift, ie increasing...
exi,
another form of the RH rule which you may find easier is to point your thumb in the direction of the charge's velocity vector. The point your fingertips in the direction of the B field. Finally, the force on a positive charge is in the direction your open palm is facing. If the charge...

An astronomer observes a hydrogen line in the spectrum of a star. The wavelength of hydrogen in the laboratory is 6.563 x 10-7m, but the wavelength in the star’s light is measured at 6.56186 x 10-7m. Which of the following explains this discrepancy?
A) The star is...
Homework Statement
Assuming equal masses, how would the detection times of 3H+ and 3He+ compare [as they're both accelerated toward a detector in the direction of a constant E field]?
A) 3H+ would have a longer flight time than 3He+.
B) 3H+ would have a shorter flight time than...
1) When we insert dielectric between plates, plates can "hold" a greater quantity of charge since capacitance is increased.
But when capacitance increases, does it require that voltage decreases? (From the formula C = Q/V, capacitance and charge could increase while voltage remains...
