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

Red_shift = (

Λ

L

- (0.005 *

Λ

Λ

))/ (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

hope this will help you
