a. amplitude = 24.44
= 2.22mm
★
b. V=fλ
λ = 0.340754×1001 × 7542π
λ = 342π
★
c. ω=2πf = 754
⟹
f = 2π754
★
d. V = κω
V = 0.340754 cm/s
V = 0.340754×1001 m/s
★
e.
We use 2sinAsinB=cos(A−B)−cos(A+B)
On comparing we got
2.22[2sin(0.0340x)cos(754t)]
On solving we got
First function- 2.22cos(0.0340x−754t)
second function −[2.22cos(0.0340x+754t)]
★
f.
No⟹ length of the function is not given
