d
b
c
12. The wavelength of this wave is……………………………….
13. The period is ……………………….
14. The amplitude, or displacement, is……………….. in both graphs
15. Any two points on a wave that are in phase………………….. Any two points on a wave that are
out of phase…………………..
17.Sketch the result for each of the two cases ,when the centers of each of the two wave pulses lie exactly overlap .and
write the name of each case
16.Fill the table with suitable word :
Refraction - reflected wave - wave pulse - a surface wave -longitudinal wave
is a single bump or disturbance that travels through a medium.
1
The disturbance is in the same direction as, or parallel to, the direction of
the wave’s motion.
The change in the direction of waves at the boundary between two different media
2
