Use the Rayleigh criterion to estimate how far away (in km) you could be from the red taillights of a car and still distinguish them as separate lights. Assume that the lights are separated by 1.3 m, that the pupil is about 4.0 mm in diameter, that the wavelength is 650 nm, and that the intensity of the lights is sufficiently large that you can still see the car.

Answer:

The value is  [tex]r = 6557 \ m[/tex]

Explanation:

From the question we are told that

     The separation between the light is  [tex]s = 1.3 \ m[/tex]

    The diameter of the pupil is [tex]d = 4.0 \ mm = 0.004 \ m[/tex]

    The wavelength is  [tex]\lambda = 650 \ nm = 650 *10^{-9} \ m[/tex]

   

Generally from Rayleigh criterion can be mathematically represented as

         [tex]r = \frac{s * d }{1.22 * \lambda}[/tex]

Here r is the distance you could be from the red taillights of a car and still distinguish them as separate lights

 So  

         [tex]r = \frac{1.3 * 0.004 }{1.22 * 650 *10^{-9}}[/tex]

=>     [tex]r = 6557 \ m[/tex]

Using the Rayleigh criterion 6.557 Km away you could be from the red taillights of a car and still distinguish them as separate lights.

Given :

  • The lights are separated by 1.3 m, that the pupil is about 4.0 mm in diameter, that the wavelength is 650 nm.
  • The intensity of the lights is sufficiently large that you can still see the car.

Given that the separation between the light is, s = 1.3 m, the diameter of the pupil is, d = 0.004m, and the wavelength is, [tex]\lambda[/tex] = 650 nm.

The mathematical expression of the Rayleigh criterion is given by:

[tex]r=\dfrac{s\times d }{1.22\times \lambda}[/tex]

Now, put the values of known terms in the above equation.

[tex]r = \dfrac{1.3\times 0.004}{1.22\times 650 \times 10^{-9}}[/tex]

r = 6557 m.

So, using the Rayleigh criterion 6.557 Km away you could be from the red taillights of a car and still distinguish them as separate lights.
