Answer:
200 nm is the thinnest film that produces a strong reflection for green light with a wavelength of 500 nm
Explanation:
If two reflected waves interfere constructively ,strong reflection is produced. Two reflected waves will experience a phase change
For constructive interference
for thinnest film m=1
refractive index should be taken for film n=1.25
thickness of the thinnest film is
1. true is the answer
2. The correct option is this: FIGURE II AND FIGURE IV ARE BOTH COMPOUNDS.Figure two and figure four have components that are of different colors, this means that different atoms had combined together to form a compound.3. dont know yet
4. The figure is a molecule and an element is the correct answer
5. Elements
6. Co2
7. Both are made of two or more atoms.
8. the answer is atom
No light does not need medium to travel.Its an electromagnetic(EM) wave.All EM waves travel independent of medium. In contrast mechanical waves need a medium,sound waves,shock waves are mechanical and they need medium to transfer energy or travel.
