why do we do it?
to measure
wavelength
,
frequency
+
speed
of
water waves
equipment needed?
ripple tank
, lamp,
vibrating bar
, power pack, water, ripple tank, white paper.
bar vibrates = waves on surface
phone to record
method
place a ruler on the paper - freeze image
measure the
distance
between one wave and ten waves further = total of ten wavelengths
to find the
frequency
, place
timer
next to the paper and count the number of waves passing a point in one second.
easiest to count number in 10 seconds then divide by 10
