Question

Laser eye surgery uses ultraviolet light with wavelength 193 nm. What's the UV light's wavelength within the eye's lens, where n=1.39?

Answer 1

The wavelength of the UV light within the eye's lens, where n=1.39, is approximately 139 nm.

Step-by-step explanation:

In laser eye surgery, the ultraviolet light with a wavelength of 193 nm is used.

Within the eye's lens, where the refractive index (n) is 1.39, the UV light's wavelength can be calculated using the formula:

Wavelength in the lens = Wavelength in air / Refractive index

Substituting the values:

Wavelength in the lens = 193 nm / 1.39 = 139 nm

So the UV light's wavelength within the eye's lens, where n=1.39, is approximately 139 nm.
