Explanation:
Given
:
Time
=
t
s
Distance
=
x
m
y
=
A
c
o
s
240
(
t
−
x
/
12
)
Distance
=
0.5
m
y
=
A
cos

(
240
t
−
240
x
12
)
To find the wavelength
,
k
=
240
/
12
k
=
20
k
is Wave number
.
λ
=
2
π
/
20
λ
is the wavelength
.
0.5

λ
=
θ

(
2
π
/

)
=
θ
/

π
θ
=

0
The phase difference between two positions
0.5
m
apart is
10
0
Hence,
option
(
C
)
is correct answer.
