Answer: 117.8 nm
Explanation:
Given,
Nonreflective coating refractive index : n = 1.21
Index of refraction: 
= 1.52
Wave length of light = λ = 570 nm = 
Hence, the minimum thickness of the coating that will accomplish= 117.8 nm
Answer:
Diffraction
Explanation:
Diffraction is the bending of waves around obstacles and openings. The amount of diffraction increases with increasing wavelength.
The answer is 125 Joules
The first thing to take note of is the work equation: W=F×D
Since we already have our force and our distance that will help make this problem easier.
So, W=25*5
W=125
Therefore, our answer is 125 Joules since work is measured in joules
Hope this helped!! :)
Mass always stays the same therefore it can’t be c and d. Volume stays the same because she is not removing anything. Therefore it is a
