The non reflective coating on a camera lens with an index of refraction of 1.29 is designed to minimize the reflection of 636-nm light. If the lens glass has an index of refraction of 1.56, what is the minimum thickness of the coating that will accomplish this task

The  minimum thickness is    

Explanation:

From the question we are told that

   The  refractive index is  

    The  wavelength of the light is  

    The  refractive index of the glass lens is  

Generally the condition for destructive interference of a films is  

for  minimum m =  0  

=>    

=>      

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
