(a(i))[3]
On Fig. 10.1, enter the names of parts B, D, E and F in the spaces given.
(a(ii)-1)[1]
State the purpose served by part B.
(a(ii)-2)[1]
State the purpose served by part D.
(a(iii))[1]
State the useful energy change that happens as electrons strike the screen of the c.r.o.
(a(iv))[2]
Describe how the c.r.o. turns the spot into a horizontal line.
(b(i)-1)[1]
Determine the maximum voltage.
(b(i)-2)[2]
Determine the time for one oscillation.
(b(i)-3)[2]
Determine the frequency of the sound wave.
(b(ii))[2]
The c.r.o. settings stay unchanged. On Fig. 10.2, sketch the trace of a sound wave with a smaller amplitude and a lower frequency.
