A) determine the wave's amplitude.
B) Determine the wave's wavelength.
C) Determine the wave's frequency.
D) Determine the wave's speed of propagation.

Explanation / Answer

a)wave's amplitude. =6.2 T (ans)

b) wave's wavelength. =L =27cm =0.27m (ans)

c)wave's frequency. =1/T =1/4*10^-2 s =25 Hz (ans)

d)wave's speed of propagation. =L/t =0.27*100/4 = 6.75 m/sec (ans)
