Step-by-step explanation:
i used process of elimination... 1 and 2 looks unreasonable, and 4 doesn't work cus i tried it irl. i might be wrong though, don't rely on me :>
Answer:
-> -0.6, 1/16, 1/8, 1/2
Step-by-step explanation:
Since 0.6 is negative, that would be the most smallest value. All of the fractions have a numerator of one, so the bigger the denominator, the smaller the value of the fraction is.
The thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.
From the question we know that :
n = 1.30
λ = 500nm = 5 x 10¯⁷m
The non-reflective coating system is applied on glass and the refractive index of that system should be <em>nair</em> < <em>ncoating</em> < <em>nglass. </em>The light travels across the air and is refracted by coating film and then refracted again by the glass. For preventing the light got reflected by glass, the thickness of the layer should obey this equation :
2nt = λ/2
t is the thickness of the layer, λ is the wavelength and n is the refractive index of the film.
By substituting the following equation we get
2nt = λ/2
t = 1/4 . ( λ / n )
t = 1/4 . ( 5 x 10¯⁷ / 1.3)
t = 9.62 x 10¯⁸ m
Hence, the thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.
