Two flat glass surfaces are separated by a 150-nm gap of air. A. What wavelength light illuminating the air gap is reflected brightly?
B. What wavelength of radiation is not reflected in the air gap?

a. 600 nm

b. 300 nm

Explanation:

According to the question it is given that there is two flat glass surface that is separated by 150nm air gap

Based on the above information

The computation is shown below

a. The bright thickness is

= 600 nm

b. The dark thickness is

= 300 nm

6/12=1/2
