The Large Hadron Collider is a particle accelerator that may be able to provide insight into the most fundamental structure of matter. It is 27 km long. If the wavelength of red light is 650 nm, how many wavelengths does a photon of red light travel when it passes from one end of the collider to the other?

Answer :

4.2 × 1010 wavelengths

Answer:

[tex]4.15\times 10^{10}[/tex] number of red wavelength of red light will pass through the 27 km long collider.

Explanation:

Wavelength if the red light = 650 nm

Length of the the Large Hadron Collider = 27 km = [tex]27\times 10^{12}nm[/tex]

[tex]1 km = 10^3 m[/tex]

[tex]1 m = 10^9 nm[/tex]

[tex]1 km = 10^3\times 10^9=10^{12} nm [/tex]

Number of  wavelengths of red light when it passes from one end of the collider to the other:

[tex]\frac{27\times 10^{12} nm}{650 nm}=4.15\times 10^{10}[/tex]
