. We know that moment(m an' energy have to &e conserve' in
every event. *ow is it possi&le to conserve&oth energy an'
moment(m when a photon colli'es3 with a "ree electron?
. *ow wo(l' things change i" the photon was not a&sor&e'
&y the electron+ &(t was scattere' o"" o" it?-0e"lection
an' re"raction are 4(st special types o" scattering.) Conserve
energy an' moment(m.
5. et!s look at a pict(re o" this event an' "ig(re o(thow we
wo(l' write the e6(ations to conserve
energy an' moment(m.
7. Elastic scattering o" 89rays was o&serve'
an' explaine' &y the American physicist Arth(r *.
Compton in 172$. et!s investigate what he"o(n'. :he 'otte' line
on the graph shows
meas(rements o" 89rays that came 'irectly "rom
the so(rce. :he soli' line on the graph shows
meas(rements o" 89rays that were scattere' o"" o" a
graphite &lock. What is 'i""erent a&o(t the 'ata
recor'e' in the two lines?
1%. Why wo(l' it &e &etter to per"orm this experiment
with 89rays instea' o" visi&le light?
