Question

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 1

4.2 × 1010 wavelengths

Answer 2

`4.15* 10^(10)` number of red wavelength of red light will pass through the 27 km long collider.

Step-by-step explanation:

Wavelength if the red light = 650 nm

Length of the the Large Hadron Collider = 27 km =
`27* 10^(12)nm`

`1 km = 10^3 m`

`1 m = 10^9 nm`

`1 km = 10^3* 10^9=10^(12) nm`

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

`(27* 10^(12) nm)/(650 nm)=4.15* 10^(10)`
