Look at how the refractive indices are related at each surface.xamy said:Homework Statement
A camera lens (n = 1.29) is coated with a thin film of magnesium fluoride (n = 1.71) of thickness 87.0 nm. What wavelength in the visible spectrum is most strongly transmitted through the film?
Homework Equations
λ = 2nt/m
The Attempt at a Solution
λ = 2(1.71)(87E-9m)/(1) = 297 nm
Answer is not correct. Please point out the mistake. Thanks
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. It ranges from approximately 380 to 740 nanometers in wavelength and includes all the colors of the rainbow.
The most strongly transmitted wavelength in the visible spectrum varies depending on the medium through which the light is passing. However, on average, green light with a wavelength of around 550 nanometers tends to be the most strongly transmitted.
Green light is most strongly transmitted because it falls within the peak sensitivity range of the human eye. Our eyes have specialized cells called cones that are responsible for color vision. These cones are most sensitive to green light, allowing us to see it more clearly than other colors.
Yes, the most strongly transmitted wavelength in the visible spectrum can be changed by altering the medium through which the light is passing. For example, water and air have different refractive indices, which can affect how strongly different wavelengths are transmitted.
The most strongly transmitted wavelength in the visible spectrum is measured using a spectrophotometer. This device measures the amount of light that is transmitted through a sample at different wavelengths, allowing us to determine which wavelength is most strongly transmitted.
