Wave 1 a) How many waves are there in this wave train?
b) Wavelength cm c) Amplitude
cm

see below

Explanation:

a wave means one complete wave which is 1 period

so a) 5 complete waves

wavelength is the shortest distance between any two points in phase

so wavelength = 1 CM

amplitude of a wave is the maximum displacement of a particle from its rest position

so amplitude = 3 CM

hope this helps

hope it
