Pulse Box K 1017341
The pulse box is for generating electrical square-
wave pulses by means of a button. These are then
output from the two output sockets, e.g. to a
speaker.
The pulse box is particularly suitable for use in
sample experiments using Kundt's tube to estab-
lish the speed of sound in various media.
The pulse box itself is supplied with a 9-V bat-
tery and an instruction manual.
