#"please look at the fallowing explanation."#

Explanation:

#"Since the wave crest labeled with Y is formed after 4 seconds"##" from X, X travels 6 cm in 4 seconds."#
#"The propagation speed of the waves can be found."#

#v=x/t=6/4=1.5 (cm)/s#

#"There are 5 wave crest between X and Y."#

#5*lambda=6#

#lambda=6/5=1.2 cm(" wavelength")#

#v=lambda/T#

#T=lambda/v#

#T=(1.2)/(1.5)=0.8 "sec( Period)"#
