A refractive index of 1.6 is placed in a medium with a refractive index of 1.4, the wavelength of light passing through the mica sheet is:

To calculate the wavelength of light passing through the mica sheet, we can use the formula:

wavelength in medium = wavelength in vacuum / refractive index of medium

Since the mica sheet is placed in a medium with a refractive index of 1.4, the wavelength of light passing through the mica sheet will be:

wavelength in medium = wavelength in vacuum / 1.4

To find the wavelength in vacuum, we need to know the wavelength in the medium. However, this information is not provided in the given question. Without the wavelength in the medium, we cannot calculate the wavelength in vacuum and therefore cannot determine the answer.
