Answer:
None of the wavelength is in the visible range
Explanation:
Constructive interference of the reflected waves for different wavelengths can be estimated using:
λ
= 2nd/m
where m is 1,2,3, ...
Therefore:
m=1, λ
= 750 nm
m=2, λ = 750/2 = 375 nm
The limits of eye's sensitivity is between 430 nm and 690 nm. Beyond this range, the eye's sensitivity drops to approximately 1% of its maximum value.
The atomic number of the atom is 13. This means that its electronic configuration is (2 8 3) or in other words:
1<span>s2, </span>2<span>s2, </span>2<span>p6, </span>3<span>s2, </span>3<span>p<span>1
If three electrons are lost, then these electrons are removed from the outermost level.
In our case, electrons are removed from the third energy level (one electron is removed from the 3p orbital and two electrons are removed from the 3s orbital).</span></span>
Answer:
C. Protons are positive, neutrons are neutral, and electrons are negative
Rays of the light fast moves to the water and to the fish and then they are reflected
<u>Explanation:</u>
- The movement of the light in the water and which to the fish taste of thence they are reflected by the upper surface of the water and reaches the eye, this results in The refraction in the lens of our eyes and it reaches the retina.
- The retina consists of the photosensitive pigments that helps in the giving off the lights when the electrochemical neuronal activity reaches the brain of human beings
