Answer:
Red-Shift = (
Λ
L
-
Λ
O
)/
Λ
O
Here,
Λ
O
is the Observed Wavelength.
Λ
L
is the Wavelength measured in a Laboratory.
Now the Observed wavelength is 0.5% longer than the wavelength measured in a Lab.
Λ
O
= 0.005 *
Λ
L
+
Λ
L
Red_shift = (
Λ
L
- (0.005 *
Λ
L
+
Λ
L
))/ (0.005 *
Λ
L
+
Λ
L
)
Red_shift = (
Λ
L
- 0.005
Λ
L
-
Λ
L
))/ ((1.005
Λ
L
))
Red_shift =-0.004975
Speed = Red-Shift * Speed of Light.
Speed = 0.004975 * 300000 km /sec
